Description
The Open Throttle ValveTech™ Titanium Big Dual exhaust system pairs a twin 3-inch midpipe and H-pipe with a valve-controlled 3.5-inch cat-back, giving your G80 M3 or G82 M4 a powerful, aggressive note across the entire rev range.
With the valves open, exhaust gases flow freely for a full, aggressive sound. With the valves closed, the quad-chambered muffler directs the exhaust through the inner two tips for a quieter drive.
The system mounts to the factory points, with no cutting or welding needed, and it’s fully reversible to the factory exhaust.

- Direct replacement: fits in place of the factory exhaust system
- Grade 3 titanium: lightweight and built to last
- TIG-welded joints: clean, high-quality welds throughout
