AFE power introduces the MACH Force-XP down-pipe back exhaust system for the for 2015-2016 BMW M3/M4 (F80/F82) with 3.0L Twin Turbo S55 engine. This system is constructed from 100% TIG-welded, 2-1/2" mandrel bent 304 stainless steel tubing for maximum flow. In for testing, the cat-back exhaust system resulted in gains up to +15 horsepower and +27 lbs.-ft. of torque, as measured on AFE's in-house dyno (tested on a for BMW M4 (F82) with the AFE power (Street) down-pipe P/N: 48-36312). Included in this exhaust system are dual high flow transverse mufflers for increased flow and performance across the power band while maintaining a great tone. The mufflers comes with a unique high-temp powder-coated black finish finish for an aggressive style. aFe also has incorporated an equalizer balance tube to evenly distribute exhaust pulses traveling through the exhaust system. This not only creates a more efficient flow and better performance but also reduces decibels for minimizing exhaust drone. To finish off this system are quad 3-1/2" diameter, carbon fiber, tips with CNC-machined laser-etched inserts for an aggressive style. All factory mounting locations are retained to provide a simple, hassle-free installation with no modifications necessary.

Aggressive Sound:

This system includes dual free-flowing, high-temp powder-coated black transverse mufflers to absorb high pitch tones producing a powerful sound, virtually eliminating drone.

Equalizer Balance Tube:

The equalizer balance tube evenly distributes exhaust pulses traveling through the exhaust system. This not only creates a more efficient flow and better performance, it also reduces decibels for minimizing exhaust drone.

Simple Installation:

This MACH Force-Xp down-pipe back exhaust system uses factory mounting locations providing stability and a hassle-free installation.

Quad 3-1/2" Tips: 

Finishing off this system are quad light weight, 3-1/2”diameter, polished tips. The tips come with CNC-Machined laser-etched inserts, which give an aggressive yet elegant sporty look.

Leak-Free Seal:
