I have a B18C1 with a supercharger on it. Is a 2.5" thermal catbackbig enough? I believe it is but just making sure

 

i've heard 2.5" works good for both N/A and F/I

 

Aight. I dont want to go up to 3" because of the noise. Its actually decently quiet. Which i like cause i HATE ricy sounding cars

 

it should sound better if its larger. it'll sound lower. the thing that makes a car sound ricey is 1) no resonator 2) ebay muffler

 

05civic....you sure man? Ive heard a lot of the ricy sounds comin from a huge pipe and a n1 muffler and the stuff like that. Haha i already have the whine of supercharger i dont want anythin else on top of that. Its actually decently throaty now.
