The aFe MACHForce-XP exhaust for either your F30 328i (N20) and F32 428i (N20) delivers power gains plus it has an aggressive sound when you want it and a mellow tone when you’re cruising. aFe measured 6hp and 8ft-lb gains on their dyno with this exhaust alone. This high-quality, free-flowing exhaust system is constructed of durable, mandrel-bent 304 stainless steel tubing and TIG welding for long, trouble-free life.
Designed for maximum performance, aFe’s exhaust utilizes a high-flowing pipe and muffler layout to minimize restriction. The larger tips fill out the rear valance and hint at the greater performance within. Note: some trimming of the plastic valance may be required.
Not for N26 SULEV models.
Note: This exhaust system is designed to change the tone and increase the volume of the exhaust. Some states or jurisdictions have strict sound regulations that prohibit any changes to the factory exhaust. It is the responsibility of the vehicle owner to ensure his/her vehicle complies with all federal, state, county, or local regulations. Installation of this exhaust will not increase emissions nor cause a check-engine light or fault codes on a properly maintained vehicle. It was developed to work with all factory emissions controls and equipment.
