New G01/G02 M40i Resonator Delete
Unleash the full potential of your B58 while retaining the factory-valved rear muffler. The Turner Motorsport Resonator & Center Muffler Delete replaces the restrictive factory center section with lightweight, high-flow 304 stainless steel tubing, unlocking a deeper, more aggressive tone and improved exhaust flow.
This direct bolt-on upgrade sheds about 5 lbs, smooths exhaust routing, and eliminates factory bottlenecks for better performance and sharper sound. Fully compatible with the stock downpipe and rear muffler, it�s an easy, reversible way to add excitement to your M40i without replacing the entire system.
Deeper, more pronounced exhaust note without the drone
