Our exhausts have earned praise from owners and the press alike, due to their unique “Jekyll and Hyde” personality. We spend considerable time and effort during development to achieve remarkable civility when idling and at part throttle cruising, while also producing a war-cry wail when full throttle is applied. Our exhausts are like bespoke suits: each is hand made utilizing only the finest casing and packing materials, and they command respect without calling unwanted attention to themselves. Sophisticated, refined, and powerful, all at once.

Whether you’re looking for full blown roar with our Track Edition Exhaust System or a more subtle lower decibel with the Touring Edition Exhaust System, our two A4 exhaust editions provide a solution for every discerning owner.

Each cat back system features an H-pipe crossover tube at the front to maximize exhaust scavenging for maximum power, as well as to take a harsh edge off the exhaust sounds. Tubing diameter for the entire system is 2.25″.

A4 3.2L Track Edition Exhaust System

The business end of this exhaust is not for the faint of heart. Dig into the throttle and you’ll realize why we call this the “track edition.” This is a loud exhaust, with potential for drone due to the strategic elimination of certain resonators. Family drivers and client entertainers, we suggest the Touring exhaust.
