STaSIS SE121-E10-01-00 Cat-back Exhaust for Audi B7 S4

The STaSIS B7 S4 cat-back exhaust offers perfect blending of aggressive sporty tones when you want it and quiet cruising when you don't, making this the perfect performance street exhaust system. This is the same system that we include on our Signature Series edition S4's featured in Quattro Quarterly and offered exclusively through Stasis Signature series Audi franchised dealers.

The tuned resonance chambers in the STaSIS exhaust eliminate the need for separate resonators, keeping the weight of the STaSIS exhaust lower than the competition. V-band clamps allow easy installation and provide the extra advantage of not needing to remove the entire catback system if downpipes are added at a later time. The STaSIS exhaust provides one of the fastest and trouble free installs available.
