The aFe MACH Force XP axle-back exhaust for 2012–2015 BMW 335i (F30) with N55 turbo engine is a bolt-on upgrade that produced roughly +4 horsepower and +5 lb-ft of torque in testing. Designed with carefully chosen tube diameters and lengths to maximize response, it uses mandrel-bent, TIG-welded stainless construction and finishes with dual laser-etched 3.5" polished stainless tips for a refined, aggressive tone.
