Question about this product?

We're happy to help.

Enhance exhaust performance, sound, and throttle response on your BMW M3 (G80 / G81), BMW M4 (G82 / G83), BMW M4 CSL (G82) or BMW M3 CS (G80) with the Supersprint Non-Resonated J-Pipe. Engineered as a high-flow center section upgrade, this precision-built J-Pipe replaces the factory center pipe and secondary catalytic converter to deliver improved exhaust flow, increased power potential, and a deeper, more aggressive exhaust note.

Manufactured from premium T304 stainless steel, the Supersprint J-Pipe features a 100mm mandrel-bent cross section designed to reduce backpressure while maintaining excellent fitment and long-term durability. The non-resonated design allows the S58 engine to breathe more freely, resulting in a sharper, race-inspired tone.

This J-Pipe is designed to integrate seamlessly with the OEM primary catalytic converters, allowing for a straightforward installation while retaining factory mounting points and alignment. Every Supersprint exhaust component is hand-crafted in Italy.
