These two companies make cat-back system for the A4 3.0 Quattro. The Thermal costs $899.00 and the Milltek costs $1195.00. They both are full stainless steel. If you have either of these systems please share your experience and why you pick it.

Thanks!!!!

i beleive thermal is louder and will give you more power gains. miltek is considered to be fairly quiet with less power gains!

There're others, like Supersprint, Eisenmann and Neuspeed.

don't know if there's a sound that you're trying to go for, but it's something to think about

I am thinking Thermal R&D street version. I have sat in Chekm8's 1.8T and like the sound of it but it's bit loud sometime.

i'll be honest that i haven't heard the thermal, but if you think it might get too loud then Milltek sounds like the right exhaust for you...either that or APR

Deep throaty is AWE/Thermal, I hear a Milltek and it's just a shade louder than stock.
