aFe Mach Force XP Cat-Back Exhaust 49-36317-C – BMW M5 (F10)

OVERVIEW

aFe POWER's MACH Force-Xp cat-back exhaust system was developed for the twin-turbo F10 M5. In aFe's testing the system produced +18 horsepower and +30 lbs. x ft. of torque. It is constructed from TIG-welded, 3" mandrel-bent 304 stainless steel and uses a quad high-flow muffler layout, with tube lengths tuned to maximize performance across the power band while maintaining a great tone.

An X-pipe balance tube equalizes and evenly distributes exhaust pulses, increasing flow and performance while minimizing exhaust drone. Mitered merge collectors reduce turbulence and increase exhaust velocity, which raises horsepower and torque and sharpens throttle response. High-quality OE-style flanges and band clamps give a complete 360-degree sealing surface.

Finishing the system are four 4" carbon fiber tips with 303 stainless steel machined-finish inserts — race inspired, lightweight and built to handle extreme temperatures and weather. The exhaust uses all factory hanger locations for a hassle-free installation with no modifications necessary. All aFe exhaust systems are engineered and manufactured at aFe's Corona, California facility.
