i just bought some quiet thunder mufflers and i have a catted x pipe and spintech pro streets right now, my question is with the high flow cats how loud is this cat-back? i removed my magnaflows because it was too quiet and bought spintechs because of price, i have always wanted bassani since i only hear good things but in cali i have never heard a 5.0 with it, well i got the mufflers dirt cheap and was wondering if they still sound good with cats? thanks.
