The aFe MACHForce XP axle-back exhaust for 2015–2021 BMW X1 2.0L turbo is a stainless steel system that replaces the factory axle-back section for improved flow and sound. It uses mandrel-bent 3" to 2.5" 304 stainless tubing, a high-flow polished muffler and dual 4" black clamp-on tips. The system mounts to factory hangers, incorporates the factory-style exhaust valve (factory motor not included), and is 100% MIG-welded for strength while aiming to free available horsepower and sharpen throttle response.
