carsound cat question
hi i just ordered my greddy evo2 exhaust system for my '95 gsr and was planning on buyin a carsound cat also. i wanted to know which would be better, the 2.25 inch inlet/outlet or the 2.5 and why. any help would be great thanks
Depends on the header you are using. If your header has a 2.25" outlet, use a 2.25" cat. Otherwise, use a 2.5".
I am using a 2.5" carsound with that exhaust but only because my DP is 2.5".
