Hi all my name is chris i was just wanting some advise on a exhaust system and what would you suggest. So i have a high comp b16A engine going in soon with ek9 .5 bigger pistons ek9 cams .5 skimmed head ect ect but basically im aiming for around 190 to 200bhp so i just wanted to know whats best for my setup as i had a buddy club spec 2 which i believe is 2.75 and im now running a HKS hi power exhaust and it is a 2.25 and it feel like its strangling the car a little compared to then buddy club so i thought id ask you to see what you think is the best for my setup or even a true 2.5 custom system, thanks for reading, chris.
