The aFe MACH Force XP exhaust system for the 09-12 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. All systems use factory mounting locations providing stability and hassle-free installation. High quality band clamps are used for a complete 360 degree sealing surface. 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. Eliminates vibrations transmitted from the engine and exhaust into the chassis resulting in a smooth and comfortable ride.

  • Simple Installation.
  • Leak-Free Seal.
  • Aggressive Sound.
  • Stainless Steel Flex-Pipe
  • Audi, A4, B8, L4 2.0L turbo, 2009-2012

Advanced Flow Engineering, Inc. (aFe) produces high flow, high performance air filters & intake systems for the automotive industry. Founded in April, 1999, aFe was created to address an obvious need in the automotive aftermarket industry: a lack of choice for a high performance aftermarket air filter. We are a team of engineers, machinists, production and sales people who believe in the product we design. We each have years of experience in our respective positions and together work to ensure that we have the best product on the market. Our purpose was not just to be another vendor that offers air filters, we chose to pay attention to those finer details that set an aFe filter apart from the competition.
