Our DCE Parts - BMW F97 X3M F98 X3M Single Pipe Midpipe Hybrid Titanium Catback upgrade exhausts are made from high-grade titanium. Our valved exhausts are developed for perfect drivability and comfort in mind with the valves closed, however, you can switch to a sportier exhaust note with the valves open.

Upgrade your BMW X3M or X4M (F97/F98) with the DCE Parts Single Midpipe Catback system, designed specifically for the S58 engine. This system replaces the factory dual midpipe setup with a high-flow single midpipe, reducing backpressure and enhancing exhaust velocity for improved performance and a deeper, more aggressive exhaust tone.

Unlike the restrictive OEM dual midpipe layout, the single midpipe design allows for an earlier mix of the exhaust flow resulting in an unique exhaust note. The result is sharper throttle response, more turbo sound, and a pronounced growl under acceleration—without drone at cruising speeds. This catback is a direct bolt-on upgrade compatible with stock or aftermarket rear sections.

Please note that there are multiple specifications US Spec & EU RDE and the 2019+ EU RDE II for European Spec vehicles. Send your VIN number to double check!
