We designed flow-optimized and perfectly fit downpipes, that utilize OEM split design. You can install secondary cat delete pipes with OEM primary catalytic converters and get more aggressive sound without "check engine" light. Or choose our primaries with High Flow low cell catalytic converters or go with the ultimate full catless setup for maximum performance.

The most noticeable feature of our M5 F90 downpipes is a double layer heat shielding with ceramic wool inlay, packed into the embossed 321SS foil. Right the same way as OEM converters done. It's the most effective way to keep the under-hood temperature low and protect surround parts from radiant heat. No ugly wraps, no low-efficiency thermal coats, just OEM-like stuff.
