This mandrel-bent, stainless steel, MIG-welded, exhaust system is designed using a race inspired 3-step design (2.75 IN to 2.50 IN to dual 2-1\/4 IN) increasing exhaust velocity which improves horsepower, torque and throttle response. The dual exit double walled 304 stainless steel tip gives your A4 a subtle yet aggressive stance. The single 2-1\/2 IN inlet to dual 2-1\/4 IN outlet straight through designed muffler eliminates high frequency resonance which allows for a quiet idle and an aggressive on throttle sound. This exhaust uses all factory hanger locations for a hassle-free installation.
