This high-quality midpipe is engineered to elevate your exhaust acoustics, giving your B58 a far more aggressive tone. By reducing exhaust backpressure, it sharpens throttle response and increases the vehicle’s tuning potential. The system begins with a single 3.5-inch pipe that splits into dual 3-inch pipes running all the way to the rear muffler. This diameter provides exceptional exhaust flow and lets your B58 sound exactly the way it should have from the factory.

CRT Performance blends precision engineering with easy installation, making this midpipe both a practical and powerful upgrade for your BMW.

Information for EU-market vehicles

This midpipe removes the factory OPF filters and is intended for track/off-road use only.
Removing the OPF may trigger a check engine light and limp mode.
