best catalytic converter
i have a4 2000 ls1 with mid length headers and was wondering what would be the best cat for my car. i now have carsound cats and it is very quiet now. i heard a 1999 trans am with the same headers and slp cats and it is a lot louder than my car. i need cats so what is the best cat, i still want it to be somewhat loud.
