BMW Downpipes for BMW G80 M3 S58 3.0L

Clear BMW chassis

When BMW began to offer more and more forced induction vehicles, some enthusiasts were upset and others were excited about the big power potential. While we love older, naturally aspirated BMWs, we LOVE forced induction BMWs. Upgrading your downpipe (or downpipes) is one of the easiest ways to reduce restriction and add more power to your BMW. We offer several brands, including our own designs, of downpipes for your BMW!

The BMW G8X M2, M3, and M4 represent the next evolution of M performance, powered by the highly capable S58 twin-turbo inline-6. While factory catalysts prioritize restriction and sound suppression, our NEW EPA-compliant 400-cell high-flow catted downpipes are engineered to reduce exhaust backpressure, enhance turbo efficiency, and unlock a sharper, more aggressive exhaust character — all while maintaining emissions compliance standards.
