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 over pipe comes with 2 new OEM exhaust gaskets for a fresh new seal.
Add an easy 3whp to your BRZ/FR-S with the PERRIN Overpipe. This dyno chart shows BRZ with our 2.5″ catback and 2.5″ catless front pipe installed. Then another run with the PERRIN Overpipe is installed showing a gain of 3whp.
