Active Autowerke BMW F80 F82 F87 Catless Downpipes for M2 Competition, M3 and M4
Unlock serious performance from your S55 engine with the Active Autowerke catless downpipes for the BMW F87 M2 Competition, F80 M3 and F82 F83 M4. These high quality, free flowing 304 stainless steel downpipes are engineered to remove the restrictive factory catalysts, reduce back pressure, cut radiant heat and deliver faster turbo response, stronger low to mid range torque and a harder hitting top end. If you are searching for BMW M3 catless downpipe, BMW M4 decat downpipes, F80 M3 downpipe upgrade, F82 M4 downpipe upgrade or F87 M2 Competition S55 downpipe UK, this is the proven solution from Active Autowerke.
AA spent extensive time refining these downpipes for the F8X platform. Early prototypes without flex joints created unwanted cabin vibration, so the design was reworked to include flex joints that effectively dampen vibration while maintaining durability and precise fitment. The result is a set of downpipes that look as good as they perform and fit the S55 platform properly, every time.
Why choose Active Autowerke S55 catless downpipes
- 10 to 15 hp increase when paired with the Active Autowerke F8X mid pipe
- Noticeably quicker turbo spool and improved throttle response
- Less restrictive, more free flowing for stronger low end and mid range performance
- Flex joints included to reduce vibration inside the cabin
- Manufactured from 1.3 to 1.5 mm thick 304 stainless steel
- Lighter than factory catalytic converter downpipes
- Developed for precise fitment on F87 M2C, F80 M3 and F82 F83 M4
Optional White Lightning ceramic exhaust coating by Swain Tech
For even lower engine bay temperatures and maximum efficiency, choose the optional White Lightning exhaust coating. This is a true ceramic thermal barrier applied in a molten state that bonds directly to the metal, not a thin cosmetic paint. It is applied much thicker than typical cosmetic coatings and is designed to reduce radiant heat by roughly 35 to 55 percent which helps lower intake air temperatures and keep exhaust gas velocity high for better performance. The coating has a melting point over 3,000°F and dissipates heat quickly so parts become cool to the touch far sooner after hard use. If you are chasing every advantage on your BMW M2 Competition, M3 or M4, the White Lightning coated option is the performance choice.
