A smooth and unrestrictive exhaust path after the header is key to engine power and performance. With smooth bends and larger diameter tubing, the PERRIN Performance overpipe increases flow without adversely effecting overall exhaust velocity.
The PERRIN Overpipe is made from 2.5", 304 Stainless Steel and assembled with precision TIG welding. Unlike the factory 2.118" tubing with it's sharp, crimp type bends throughout, the PERRIN Overpipe is CNC mandrel bent for smooth air flow allowing for maximum horsepower.
PERRIN Flanges are CNC machined from 1/2" thick, 304 stainless steel and counterbored on the inside for smooth transitions and a supreme seal.
Add an easy 3whp to your BRZ/FR-S with the PERRIN Overpipe. This dyno chart shows a BRZ with our 2.5" catback and a 2.5" catless front pipe installed. Then another run with the PERRIN Overpipe installed showing a gain of 3whp.
Get inside Jeff's head and learn how he designed and built the overpipe. See how the factory exhaust system lays out, how the jigs are made, why we coined the industry term "overpipe" and see the dyno charts for the proven results. HERE.

We will not warranty any exhaust part that fails or has warped flanges with header wrap installed. We will not warranty any exhaust part that fails or has warped flanges with header wrap installed. While header wrap protects the engine from heat as well as provides some performance benefits, it greatly reduces the life of any stainless steel part. Header wrap greatly increases the rate of corrosion (even stainless steel corrodes), added to that the actual temperature of the metal is much hotter, reducing its lifespan even further. Operation of vehicle without installation of splash guard will void warranty.
We will not warranty any flanges that are warped away from the weld if any aftermarket gaskets are used. Only OEM Subaru gaskets are to be used on this PERRIN Exhaust part, with the exception of downpipes for turbo kits. Subaru provides the proper crush gasket that still becomes flat when tightened (or over tightened) in comparison to aftermarket gaskets which can have a crush ring that is too think causing a hot-spot in the middle of the flange. These will warp the flanges of your PERRIN exhaust, causing a permanent exhaust leak that will not be fixable with a new gasket.
