Description
DCE Parts - BMW G29 Z4 3.0 B58 Valvetronic upgrade exhausts are made from high-grade stainless steel. Our valvetronic 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. The comfort on highway journeys is sublime, barely introducing more sound to the cabin than original. Even with the valves open, the comfort levels are surprisingly high, while the fun factor is also fantastic when you floor the throttle.
The high quality valves are durable and reliable and offer the best of both worlds in terms of sound and drivability.

Emissions & road use
Catless, cat-delete and OPF/GPF-delete versions are intended for motorsport and off-road use only. Fitting them on a road-registered vehicle may not be permitted in your country and can affect type approval, inspections (MOT/APK/TÜV), warranty and insurance. Versions with a 200- or 300-cell high-flow catalytic converter keep a catalyst in place. Always check your local regulations before fitting. Catless and delete parts are not shipped to the United States.
