Thank you for your patience. We have finalized the design for our
70R Cat-back single exhaust for the
FRS and BRZ. I believe we are the first to offer an exhaust in 70mm on the market at the moment. We have tested 2.5" pipe and we hardly see any gains so we tested with the 70 and now we talking
The exhaust is built with stainless 70mm (2.75") piping, single resonator on b-pipe and with 101mm (4") exhaust tip. We built the exhaust with horizontal muffler for better sound quality while maintaining exhaust flow. The entire cat-back system weighs 26 lbs.
Here we go
Dyno test was performed with DYNOCOM (hub dyno) and all numbers are SAE corrected. Dynoed with 5th gear which is 1:1 ratio !
The 70R exhaust gained 2-3whp across the band and 5.4whp at peak.
Now we will be finishing up building the over pipe and the secondary cat-delete pipe and we will hit the dyno again !
Here's the Video clip for the exhaust !
