The MACH Force XP exhaust system for the 2009-2015 Audi A4 (B8) L4-2.0L (t) produced 12 HP and 14 lbs. x ft. of TQ. This mandrel-bent, stainless steel, MIG-welded, the 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. No modifications are necessary.
