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.

Carsound cats happen to be one of the best cats out there. I'd say keep them and look for sound somewhere else.

the cats that SLP sells are made by Bassani, so you might want to look them up and see if you can get a better deal.

Interesting...I always thought SLP used Random Tech and Bassani used Catco.
