Sku # : aFe-Exhaust-Audi-A4-B8-ER3
Allow your Audi A4 B8 to be released to its full potential with this aFe MACH Force XP exhaust system.  This cat-back exhaust produces a huge 12 horsepower and 14 lbs. x ft. of torque.  aFe's engineers designed this system using a race inspired 3-step design 2.75” -  2.50” - dual 2.25” increasing exhaust velocity which improves horsepower, torque and throttle response.  It is made out of mandrel bent, stainless steel, MIG-welded for maximum durability and strength.
