What Owners Say
Owners and enthusiasts consistently praise the aFe Mach Force cat-back for its deep, throaty sound that's noticeably louder than stock without being obnoxious, with plenty of burbles and pops that deliver an aggressive tone from behind. The construction quality earns high marks, with solid build and clean integration with OEM valve control on applicable models. Dyno-tested performance gains of +11 horsepower and +17 ft-lbs of torque back up the acoustic improvements. Some note the burbles can diminish during normal driving, and a few mention it lacks the pronounced DCT shift "burp" found on competing systems. Overall, the aFe exhaust has built a strong reputation among BMW owners seeking quality construction and authentic performance sound.
