Upgrade the exhaust system on your BMW G8X M3 or M4 with the Supersprint J-Pipe Resonator Delete Package for the OEM rear muffler. Engineered as a direct-fit replacement for the factory secondary catalytic converters and resonators, this package reduces exhaust restriction while enhancing the tone and character of the S58 engine without replacing the factory rear muffler.
Manufactured entirely from premium T304 stainless steel, every component is precision mandrel bent and TIG welded to deliver exceptional durability, corrosion resistance, and OEM-quality fitment. Developed through decades of motorsport engineering, Supersprint exhaust systems are designed to optimize exhaust flow while maintaining long-term reliability.
This complete package includes non-resonated front J-pipes, a secondary resonator delete center H-pipe, and all required connecting clamps for installation. Whether paired with the factory rear muffler or used as the foundation for a larger exhaust upgrade, this package provides improved flow and a more aggressive exhaust note while retaining factory mounting locations.
