BMW M8 Secondary Downpipes
The RedStar Exhaust BMW M8 Secondary Downpipes are engineered to improve exhaust flow, sound, and performance while maintaining factory drivability. Designed as a lower secondary slip-on style downpipe, this upgrade replaces the restrictive factory secondary catalytic converters with a fully bolt-on solution.
Flow-optimized for maximum efficiency and precision-fit for OEM-level installation, these secondary downpipes install seamlessly with no check engine light or error code issues. The result is a more aggressive exhaust note, improved response, and a more engaging driving experienceโwithout the complexity of primary downpipe replacement.

Available Options:
- OE-style Heat Shielding with ceramic inner liner - signature REDSTAR thermal management feature that reduces radiant heat from the exhaust pipes up to 70-80%. Being inspired by racecar engineers who uses it alot, we moved heat shielding to the tuning industry and made it available as an option for any REDSTAR products. Usual thermal wraps or ceramic coatings are not even close in effectiveness and durability to our Heat Shielding. Please be aware of fake shielding when it is nothing but foil wrapped around the pipe. Without a sufficient ceramic wool layer inside and properly embossed foil it will not work as expected.
