BMW Exhaust Center Sections

Unlock the true potential of your B58 while retaining the functionality of the factory valved rear muffler. The ECS Tuning Center Muffler Delete replaces the restrictive OEM midsection with high-flow, TIG-welded 304 stainless steel tubing, improving both exhaust flow and acoustic character.

This direct-fit upgrade removes the factory resonator and center muffler, reducing system weight by approximately 8 lbs and eliminating built-in restrictions that limit performance. The result is a deeper, more aggressive exhaust tone with enhanced burbles, delivered without unwanted drone.
