aFe introduces the MACH Force XP exhaust system for the 2012-2017 BMW M5 (F10) twin-turbo S63. In recent testing this system produced 18 horsepower and 30 lbs. x ft. of torque. This unique exhaust system is constructed from TIG-welded, 3" mandrel bent 304 stainless steel and uses quad, high-flow mufflers. This system was designed and engineered by tuning the perfect tube lengths, ultimately maximizing performance across the power band while maintaining a great tone. Also included is an X-pipe balance tube which equalizes and evenly distributes exhaust pulses for increased flow and minimizing exhaust drone. To finish off this system, aFe uses four 4" polished tips with 303 stainless steel machined finish inserts. This exhaust uses all factory hanger locations for a hassle-free installation. No modifications necessary.

X-Pipe Balance Tube:
An X-pipe balance tube is used to equalize and evenly distribute exhaust pulses which minimizes exhaust drone and increases flow and performance.

Mitered Merge Collectors:
Mitered collectors decrease turbulence and increase exhaust velocity resulting in increased horsepower, torque and improved throttle response.

Leak-Free Seal:
High quality OE style flanges and band clamps are used for a complete 360 degree sealing surface.

Quad Muffler Design:
Free-flowing mufflers are used to absorb high pitch tones producing a powerful sound and unleashing all available horsepower and torque.

Simple Installation:
All systems use factory mounting locations providing stability and hassle-free installation.

Emissions Disclaimer:
This product does not require a CARB EO#

All aFe exhaust systems are engineered and manufactured in our Corona, California facility.
