These pipes have shown a 5-10hp increase at the wheels on factory 350z’s. By installing our Circuit Werks Test Pipes, you will not only improve dramatically the sound of your G, but you will also gain the horsepower since it’s not restrictive anymore where you would normally drive the car. Like to a local car meet, to work, or weekend cruising around town. The sound will be slightly louder since your cats are deleted but once you step on it, you can hear the deep sport tune and depending on the exhaust you have.

He is a true motorhead at heart and loves writing, especially about engines and vehicular dynamics. A noise ordinance establishes the types of noise that are and are not permitted at any given moment. I would therefore check with the local authorities to see what the laws are where you live.

Plain test pipes offer the highest level of flow, but often result in a “raspy” exhaust note between 3-4k rpm. Test pipes have always been high on the “bang for the buck” list, but the louder exhaust tone can be too aggressive for some people. So we now offer a full stainless straight through converter replacement, but with a stainless exhaust resonator welded in-line. The exhaust note will only be slightly louder, and have a slightly deeper tone.Catalytic converters are the biggest “choke” point in the exhaust.

Buyer assumes all risk of injury or loss which may result from using this product in a manner for which it is not intended. They have bigger cross-sections inside the ceramic honeycomb structure, which is also known as high-flow cats.

Although a test pipe is not something we advise doing, especially for daily driving, you can think about it if you want to get the most out of your exhaust system. This is mostly because turbos rely a lot on exhaust pressure, so it’s easy to see why improving the exhaust flow on a turbo engine responds much better to a test pipe configuration. Your turbo might end up making more boost, which can be both bad or good, depending on your engine internals, and other components. Well, when you’re fitting a straight pipe in place of the cat, you’re messing with the burn ratio. When you fit a test pipe, you lower the pressure in your exhaust, and this fools the engine into thinking that it needs to work harder to maintain that pressure. AAM Competition offers engine computer tuning (calibration), repairs, and maintenance.

Most importantly, we design & engineer high quality innovative performance products for Nissan and Infiniti. Ensure smooth performance and extend transmission life with our direct-fit BladeRunner Transmission Oil Cooler Kit, designed for easy installation and optimal cooling efficiency.

For Nissan 350Z and 370Z owners with the VQHR engine, the Fast Intentions VQHR FI Resonated Test Pipes offer a balanced approach to performance and sound enhancement.

Regulatory bodies are set up everywhere that monitors emissions from exhausts for this exact reason. This also acts as a check and balance for the throttle and fuel system, and if the sensor picks up different O2 concentrations than what’s normal, a check engine light will most likely appear on the dash. Exhaust gases are being produced at the same rate, and for this, engines need a good exhaust route as much as they need fuel and air. Talk to any engineer and he or she will tell you that getting air in and out of an engine is always a big problem.

A good example is Koenigsegg, which uses high-flowing cats in the exhaust system in every car they manufacture. Every car must come equipped with a catalytic converter by law, and depending on where you reside, it may be quite unlawful to remove this part from your exhaust system. Coming back to power figures, a test pipe is capable of increasing power output by a maximum of 10 if the engine has gone through an ECU tune also. For turbo engines, however, a test pipe setup will increase power figures by at the dyno.

With their precision engineering, quality materials, and potential power gains, these test pipes provide a satisfying upgrade to your vehicle’s exhaust system. Elevate your driving experience with the Fast Intentions resonated test pipes and enjoy improved performance and a refined exhaust note.

A catalytic converter has a different air-flow design, and hence, has different pressure values, which you’ve changed when you install a test pipe. Test pipes are pretty much illegal everywhere, as well within the USA. See, every engine uses motor oil, and often at times, motor oil gets combusted along with fuel.

YPerformance Catless Downpipe features wider capacity and no restriction to exhaust flow. Nissan 370z test pipes directs the produced exhaust gases to the exhaust system. It helps in moving the exhaust gases through the system as efficiently as possible. They didn’t take long to arrive considering they were back ordered and just got installed. They reduced the raspiness on the tone of my exhaust and paired with the right exhaust, these will sound amazing.

The factory exhaust will always have restrictions and these restrictions are normally highest near where the catalytic converter is found. Invidia Exhausts use a larger pipe diameter and smooth bends which allows exhaust gases to pass with fewer restrictions and turbulence. A High-Flow catalytic converter is then utilised to still control emissions for street driving legalities but with minimal impact to exhaust flow. In some cases Invidia will also offer catless versions for off-road use where every ounce of performance is required.

Test pipes are also sometimes confused with charged pipes, but the two are quite different from each other. Charge pipes are called so because they add an additional charge to your exhaust system. Charge refers to the air inside your cylinder, and since charge pipes direct air toward the turbocharger, the overall air inside cylinders increases significantly as a result of turbo spool.

A method of directly altering exhaust harmonics for enhanced performance and sound. No, as we mentioned earlier, test pipes and downpipes are different, downpipes come before test pipes, and they connect to the exhaust manifold. These catalysts transform exhaust gases into less hazardous fumes when they pass through and come into contact with them.

With a noticeable power gain throughout the rev-range and a polished finish, these are a perfect addition for any performance vehicle. Expect an increase in exhaust tone, due to freeing up the exhaust flow and the deletion of the catalytic converter. The aftermarket performance part replacement for the catalytic converter for Nissan and Infiniti cars. YPerfomance’s auto engineers designed, developed, and tested this custom test pipe for the past years and got the best result for the perfect performance for Nissan and Infinity cars. Far more engineering goes in to the design of an exhaust system than many realise. From a performance perspective, there is a fine balance between exhaust back pressure and exhaust gas velocity.

You can manufacture a test pipe using basic power hardware like a band saw, and precision TIG welding equipment. The relatively low cost of making a test pipe also makes it more appealing to tuners, looking to maximize their power output on a low budget. The more unrestricted your intake is the more smoothly you can get air in, and the more unrestricted your exhaust is; the smoother air exits the engine. Read our example on different air intakes for your 350z, to understand this better. Socal Z strives to offer the best in parts selection, service, and performance for your Nissan 300ZX, 350Z, 370Z, Infiniti G35, & G37.

If you’re someone who wants to maximize the exhaust flow, in your vehicles one of the upgrades is to replace the factory catalytic converters with 2.5″ diameter race or “test” pipes. The YPerformance 370Z/G37/350Z Test Pipes are specifically designed for off road performance. By eliminating the cores of the OEM converters the exhaust can freely flow from the engine resulting in an increase, in peak power output. These pipes completely remove your factory catalytic converters and replaces them with a straight through design. This provides the absolute most flow possible which has shown gains on NA 350zs between 4-8HP making it one of the best “bang for the buck” mods. They have also tended to add a “raspy” exhaust note through the 3-4k range.

Constructed entirely of stainless steel 304 tubing and polished to further enhance corrosion resistance. All TIG welding is performed with argon back purging for oxidation free welds on the inner and outer surfaces. We have a full guide on many performance test pipes for the G35. Your custom exhaust system will always be at risk of getting fined.

Expect modest increases in horsepower and torque and an increased average. Installing high-flow catalytic converters or resonant test pipes are two other potential choices to improve the sound of your exhaust, in addition to increasing the flow of your exhaust. Another solution that we will be focusing on later in this article is installing high-flow catalytic converters, but for now, let’s see whether test pipes improve performance figures. What an exhaust sounds like is typically the number one factor when choosing a system. Put a straight pipe on just about any hypercar and that distinctive engine note is lost.

The brand’s use of premium materials, combined with cutting-edge manufacturing techniques, guarantees that their parts not only perform exceptionally but also stand the test of time. Moreover, Berk Technology is known for its commitment to customer satisfaction, providing unparalleled support and service that keeps enthusiasts coming back.

This product is intended for off-road/competition use, and may not be legal for use on highway or street vehicles in your area. Some products sold by Concept Z Performance may solely be used on vehicles in sanctioned competition, which may never be used upon a public road or highway, unless permitted by specific regulator exemptions (such as CARB E.O.). The fact that it is unlawful in many places in addition to your car being a respiratory danger is another reason why you should avoid replacing your catalytic converter with a straight pipe. The exhaust gases travel through a ceramic honeycomb structure inside the catalytic converter that is made up of thousands of tiny ducts. Catalytic convertors are also necessary due to internal combustion engines’ ridiculously low efficiency. All of the hydrogen and carbon in gasoline would entirely burn out and transform into carbon dioxide and water in an ideal, frictionless engine.

Crafted from top-quality materials, they are built to last, and their bolt-on installation makes the upgrade process hassle-free. For those seeking a performance boost and a pleasing exhaust sound, these resonated test pipes from Fast Intentions are the ideal choice to elevate your driving experience. This downpipes nowadays have been shown to increase horsepower. An aftermarket downpipe with catalytic converters will add 10 to 20 horsepower on average, and that gain is noticeable anytime the turbo spools.2. Downpipes certainly will make a car louder with a more aggressive exhaust note.

High polished stainless steel, all are hand built to meet our high quality standard, then T.I.G. welded together. Megan Racing Stainless Steel Down-pipes are made of the same high-quality T-304 that is utilized in our Headers and Turbo Manifolds for extreme durability and resistance to corrosion and cracking. The missing component between any Header/Manifold and your Cat-Back system, these Down-pipes will complete the high-flow exhaust system desired for the performance of your vehicle.

Flashark ones are louder than stock because they reduce the backpressure that occurs in restrictive exhaust pipes.3. Installing an aftermarket downpipe doesn’t void your vehicle’s entire warranty. If you are a United States resident, then you’re protected by the Magnuson Moss Warranty Act. At Vivid Racing, we proudly feature a wide array of Berk Technology products, specializing in performance exhaust systems, high-flow intakes, and other essential components that significantly improve vehicle performance. Berk’s exhaust systems are engineered to deliver optimal airflow, resulting in increased horsepower and torque while providing an aggressive sound that enthusiasts crave. Their intake systems are designed to maximize airflow, ensuring your engine breathes better for improved performance and efficiency.

The principal function of a catalytic converter also referred to as a “cat” or “cat-con,” is to transform dangerous exhaust pollutants into less-toxic gases before they are released into the atmosphere. An ECU tune will correct this, and after this is sorted out, you will see higher power figures. A turbo engine will require an ECU tune more than a N/A engine since the turbo is also connected to ECU, which controls how much it spins and compresses air. All of this has to do with stock pressure values for any engine. If you own a 350z, check out these aftermarket test pipes for your car. We also have different options for the 370z, in case you’re interested.

To withstand the high temperatures laser cut cast steel flanges are used to ensure long lasting leak free reliability. This is a 100% bolt on installation for right-hand drive vehicles with no modifications or changes required. Factory O2 sensor locations are also retained where required to ensure compatibility with factory systems.

If you aspire to race your sports car, that is one of the more common reasons for replacing the downpipe. You might choose to do so simply because you are trying to get as much horsepower as possible out of your vehicle. Adding a new downpipe to older model sports cars can dramatically improve your HP. Tuning the sound of an exhaust system adds an additional layer of complexity to the performance aspect of the design process. The goal is to design a system that sounds great, without adversely affecting performance.

A test pipe will also improve torque figures, and you’re going to see the RPM jump up faster when you press down on the gas. If a lot of oxygen is present, little fuel is being injected, and the O2 sensor sends a signal to the ECU to correct this. If there is little to no oxygen present in the burn mixture, the sensor sends a different signal to the ECU, which opens the throttle body more to allow more air to flow inside the engine. Test pipes are also often used for both race and off-road use, mainly because temperatures in both of these setups exceed regular values, and thus, a test pipe is preferred. We are a team of passionate people whose goal is to improve everyone’s life.

Built as a direct OEM replacement, resonated test pipes are designed to be an addition to your cat back exhaust system. We maximize performance by eliminating your OEM catalytic converters, increasing the tubing diameter, and adding straight through perforated core resonators to free up back pressure. This addition is ideal for force inducted applications because of its straight through design, eliminating virtually all restriction.

The ECU has a lot of sensors attached to it which keep feeding it information. A good example of this case would be the oxygen sensor connected to the exhaust manifold. The sensor has the primary function of detecting how much oxygen is present in the burn mixture after combustion. To properly answer this question, we need to make sense of a few things first, but mostly the Engine Control Unit, or ECU, that’s responsible for how the engine behaves. Engine behavior is governed by a few things, which include the opening and closer of the throttle body at the intake, fuel ratio, and a lot of different stuff. For additional information on mufflers and resonators and what they’re doing in your exhaust system, read this guide.

Since this is not the case, cats are the only way to go when designing exhaust systems. Your engine’s ability to produce additional power is entirely dependent on airflow. The intake and exhaust systems are therefore frequently modified first.

This produces toxic exhaust gases, that are rich in pollutants, so a catalytic converter must be used to filter these out. If you’re looking for unbridled horsepower, modifying your standard exhaust system might be a good option. A test pipe is just a straight pipe that replaces your catalytic converter.

Whether you’re looking to improve track times or simply upgrade your daily driver, this kit provides the quality and precision engineering you need to maximize your vehicle’s potential. Trust RNJ Performance to provide the components that deliver both reliability and high performance, taking your vehicle to the next level. Although they are slightly more expensive than test pipes without resonance, they still give you a smooth exhaust flow.

This metallic mesh is coated with rare metals like platinum, palladium, and rhodium. This mesh is what actually cleans up exhaust gases, and since high-flow cats preserve this methodology, they are still viable to install in any road-legal car. Although high-flowing cats are virtually identical to standard catalytic converters, they are made to conserve power while still producing clean emissions. The catalytic converter has a honeycomb mesh inside it that causes a big hindrance in the exhaust flow.

One solution is to keep the original cat with you at your house. Test pipes are pretty easy to swap out, and cats are also relatively easy to install. Keep the test pipes for a track day, but when out on public roads, the cat is a much safer, cheaper, and greener option. Now cats can go bad because your engine’s exhaust gas temperature is high, which translates to potential corrosion. Replacing the cat is going to be pretty costly, and one cheap fix is installing a test pipe, which you can do at home.

For custom or made to order items shipping time varies as they may have to be manufactured, painted, embroidered, or assembled.

Introducing our Nissan Infiniti 350Z/370Z/G37/Q40/Q50/Q60 3.5L/3.7L HR Series Catless Test Pipes, engineered to exceed OEM standards and elevate your vehicle’s performance. Crafted with precision and built for durability, this kit offers a direct bolt-on fitment, ensuring seamless installation and optimal performance.

Normal downpipes have a catalytic converter that cleans the exhaust gases as they are produced. But g37 test pipes cause you to lose power as it has a restrictive aspect of cleaning the exhaust gases. Enhance your vehicle’s performance with our expertly designed kit, crafted to deliver noticeable power gains and a refined driving experience.

Replace it with a straight pipe, and you have your test pipe all set up. Our high flow catalytic converters will show almost equal gains, but straight throughs are a MUST for any FI application. A catless downpipe doesn’t have a catalytic converter inside, thus it doesn’t restrict the flow of exhaust gases nor does it clean it. Hence the flow of exhaust gases through a catless downpipe will be free flow and significantly higher than that of the catted downpipe. Because of these reasons, Invidia front pipes and cat pipes make for the most popular exhaust upgrade that adds a substantial bump in both horsepower and torque.

Test Pipes are fitted for one pretty obvious reason, reducing restrictions and exhaust turbulence, and increasing the ‘breathing’ rate of your engine. More air out simply means more air in, and this is what test pipes achieve. A free-flowing exhaust is just as crucial as an unrestricted air intake for your engine to operate at its best – this is where test pipes prove their worth. Nissfest 2024 is an annual celebration dedicated to Nissan and Datsun enthusiasts, bringing together car owners, fans, and aftermarket brands featuring classic Datsuns to the latest Nissan and Infiniti performance cars. AFe products are dyno tested with our in-house DynoJet, and our airflow products are also flow bench tested, for performance you can count on.

If you’re using high-flow cats, your exhaust system might just pass emissions. Another way is to just purchase a high-flowing cat system, which increases the chances of passing emissions – the one thing that drift setup owners are concerned about. Just keep in mind that one of them, resonating test pipes, is still an unlawful change. On the other hand, high-flow cats are permitted to use on public streets.

We are a team of passionate automotive enthusiasts whose goal is to improve our customers experience with their vehicle through innovative & high quality products. We engineer & build great products that make driving more enjoyable. Most of our products are proudly built here in the United States of America. You might have modified your car so that it runs at a higher boost pressure. If you have increased the amount of boost from a stock turbo system, then the increased exhaust output might demand a smooth, larger downpipe. First, a 3D scan is take of the underside of the car to ensure fitment is 100% correct.

I am using these with my stock Nismo (test pipe/cat back) system. Gave the car some room to breath and still sounds stock ( no trumpets). Resonated test pipes may also be tuned to imitate the factory exhaust note, which is what some people are after when designing their cat-back exhaust system. Depending on whether you value horsepower or environmental sustainability more, catalytic converters are either the greatest or the least critical part of your exhaust system.

We have an excellent track record in the motorsports and automobile industry. Disclaimer In effort to provide our valued clients with the most up to date and accurate information, JM Auto Racing is continuously implementing real-time updates to our online superstore.

If you looking for cheap/reliable test pipes this is one of the best choices.

While some jurisdictions that don’t monitor for emissions make it easier to get away with test pipes, others have rigorous laws and severe penalties. Currently, only 50% of the thermal energy produced by an engine when a gallon of gasoline is used is transformed into mechanical force. If 50% sounds inadequate, keep in mind that the majority of cars on the road, especially the older ones, expel over 80% of their thermal energy through the exhaust. The catalytic converter is the most limiting part of your exhaust system, as you undoubtedly already know.

Resonated test pipes are identical to standard test pipes, with the exception that a Helmholtz resonator is fastened to them. With less drone than non-resonated test pipes, they flow better than the stock cat-con and high-flow cats. Read our guide on exhaust headers vs exhaust manifolds for a better understanding. Our customers are delighted with the catless test pipe 370z system which gave an improvement in exhaust flow and horsepower.
