A "quality" exhaust system maximizes performance gains by design. 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. Test Pipes are primarily used in place of catalytic converters and are designed to completely eliminate catalytic converters to reduce exhaust drag and increase power output, typically used in track and high performance applications. What an exhaust sounds like is typically the number one factor when choosing a system.

The most common offenders by me are BMW 3 series who just endlessly accelerate and slam on the brakes for maximum pop. And they are consistently driven by the absolute worst people. What started from a one-car garage, where products were built from start to finish, has led to over a thousand products, an enthusiastic community, and many podium finishes for Martin Barkey racing. Stand out from the crowd with a high-quality performance exhaust that sounds great. Due to this items high performance nature, this product may void vehicle manufacturers warranty.

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. 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.

For out-of-stock items arriving within 30 days, you may see the authorization temporarily fall off. The funds will be placed back into your account and you won't see the pending charge from us. Once the item ships, you will see the funds deducted and the charge posted to your account.

Expect modest increases in horsepower and torque and an increased average. Installing high-flow catalytic converters or resonant g37 test pipes pipes are two other potential choices to improve the sound of your exhaust, in addition to increasing the flow of your exhaust. 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. 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. We are a team of passionate automotive enthusiasts whose goal is to improve our customers experience with their vehicle through innovative & high quality products.
