HJS ECE Downpipe BMW M135i, M2, 335i, 435i N55B30A Euro 6 90812010 (ECE)
A downpipe is one of the most popular turbo-engine upgrades. A freer-flowing exhaust side can add a sportier sound while supporting throttle response and power potential. Read more in the Futurez downpipe guide.
This product includes model-specific ECE approval. The ECE version is intended for legal road use in the vehicle applications covered by the approval.
HJS ECE Downpipe BMW M135i, M2, 335i, 435i N55B30A Euro 6 90812010 (ECE) offers vehicle-specific bolt-on fitment in place of the original downpipe. Its larger diameter and freer-flowing shape reduce back pressure after the turbocharger. This can sharpen turbo response and reduce exhaust-side thermal load, particularly on tuned engines.
