Audi has long stood for excellence, and Thermal R&Ds exhaust system for the A4 B7 is made to compliment that excellence. A 3" section coming off the catalytic converter splits into 2 sound controlling mufflers, specially designed to give this vehicle the sound it deserves. Made of 304 Stainless Steel and a polished finish, the system is capped off with two beautiful, hand made, dual wall tips exiting the back. Accompanied by a Lifetime Manufacturers Warranty, there is little reason to look elsewhere for an exhaust for this vehicle.
