The MACH Force XP exhaust system for the 2009-2015 Audi A4 (B8) L4-2.0L (t) produced 12 horsepower and 14 lbs. x ft. of torque. This mandrel bent, stainless steel, MIG-welded, exhaust system is designed using a race inspired 3-step design (2.75"-2.50"-dual 2.25") 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 2.5" inlet to dual 2.25" 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 necessary. Simple Installation: All systems use factory mounting locations providing stability and hassle-free installation.Leak-Free Seal: High quality band clamps are used for a complete 360 degree sealing surface.Aggressive Sound: A free-flowing single in and dual out muffler is used to absorb high pitch tones producing a powerful sound and unleashing all available horsepower and torque.

Stainless Steel Flex-Pipe: Eliminates vibrations transmitted from the engine and exhaust into the chassis resulting in a smooth and comfortable ride.
