Description
The aFe MACH Force-Xp Axle-Back Exhaust System with Polished Tips (afe49-36355-P) is a performance-focused exhaust upgrade designed specifically for the 2021–2024 BMW 228i Gran Coupe (F44) 2.0L turbo. This system improves exhaust flow, enhances sound, and delivers dyno-proven gains of up to +9 horsepower and +9 lb-ft of torque.
Constructed from 3-inch to 2.5-inch mandrel-bent brushed 304 stainless steel tubing, this axle-back exhaust offers exceptional strength, corrosion resistance, and long-term durability. A high-flow polished 304 stainless steel muffler maximizes exhaust efficiency while producing a powerful, aggressive exhaust tone that complements the BMW B46 engine.
This version features dual 4.5-inch polished 304 stainless steel clamp-on exhaust tips, each finished with a laser-etched aFe POWER logo for a clean, premium appearance. Factory-style hangers ensure proper alignment and a secure installation. Some cutting may be required—refer to the instruction sheet for complete installation details.
