Next, grade 304 Stainless Steel (with the exception of their titanium systems of course) is selected for all piping, mufflers and flanges. This particular grade is chosen for its strength, durability (ability to withstand the elements),and its ability to be formed and welded with relative consistency and ease. Cast flanges are then used which ensures 100% correct fitment every time, no leaks or additional stress points, and long lasting strength.

Both Test Pipes and Downpipes, like the FLASHARK G37 Test Pipes and 370Z Downpipe, are designed to increase horsepower. By improving exhaust flow and reducing restrictions, they can add 10 to 20 horsepower on average, with noticeable gains during high-performance driving. Even though they’re called test pipes, that isn’t what they do in a substantial way.
Aggressive, moderate and mild sounds to give your vehicle the voice you want. Help other Possum Bourne Motorsport users shop smarter by writing reviews for products you have purchased. When you place an order, we lose 3% due to credit card processing, and also another 3% to credit your account. The other 4% is much less then what is needed to cover all other costs and expenses lost by cancelling an order, that was already processed.
Although they are slightly more expensive than test pipes without resonance, they still give you a smooth exhaust flow. Expect modest increases in horsepower and torque and an increased average. 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. This produces toxic exhaust gases, that are rich in pollutants, so a catalytic converter must be used to filter these out.
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. Since this is not the case, cats are the only way to go when designing exhaust systems.
The goal is to design a system that sounds great, without adversely affecting performance.

Increase your vehicle’s potential with an exhaust system that’s designed to perform. Only logged in customers who have purchased this product may leave a review. Absolutely love the customer service that you get with Speedzone Performance! All my questions are always answered in such a timely manner and this a big PLUS because I live out of Florida and for them to be on top of answering all my questions in such a way means a lot. Dropped off my 2022 Subaru WRX for Exhaust, spoiler, aeroflow dynamic kit, and they killed it. We are a team of passionate people whose goal is to improve everyone’s life.
Resonated test pipes effectively increase low end torque and maximize power throughout the entire RPM band. Built as a direct OEM replacement, resonated g37 test pipes 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. These pipes replace your factory catalytic converters, letting all the exhaust pass through freely, but not the noise. Plain test pipes offer the highest level of flow, but often result in a "raspy" exhaust note between 3-4k rpm.
