We recently released our full research & development article on M5board, taking you inside Supersprint's efforts in developing the finest exhaust system for the F10 M5/F12 M6. Apart of this article were the catless downpipes, arguably the best performance enhancing modification for the F12 M6 when combined with a ECU reflash.


We received various questions regarding tuning, CEL, fitment and more. As we have just finished our first production of the catless downpipes, here are their main highlights:

1. 80mm piping diameter tapered to 70mm for a slip-fit connection
2. Can be installed with any aftermarket exhaust and the OEM exhaust
4. 304 stainless steel construction (optional inconel construction available)
