Product Details
Unleash the full potential of your B58 while retaining the factory-valved rear muffler. Our ECS 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 approximately 8 lbs, smooths exhaust routing, and eliminates factory bottlenecks for improved performance and a sharper sound. Fully compatible with the stock downpipe and rear muffler, it’s an easy, reversible way to add excitement to your X5 40i without replacing the entire system.
