BMW E90 E92 Diesel Catless Downpipe (inc. 335d, 535d & 635d)

Unlock serious flow and torque on your BMW twin‑turbo diesel with a free‑flow front section

Transform how your BMW pulls through the rev range with this high‑flow decat front pipe. Built from premium SS304 stainless steel and engineered as a precise 1:1 replacement for the factory section, it bolts straight up using the original mounting points for a hassle‑free install. By dramatically reducing exhaust restriction right after the turbine outlet, it lowers turbocharger heat soak, improves spool, sharpens throttle response and releases extra horsepower and torque.

We run this upgrade on our own builds and customer cars because it works. The difference in mid‑range punch and top‑end breathing is exactly what these straight‑six diesels deserve. Customers consistently report crisper acceleration, stronger overtakes and a more engaging sound under load.

Why this performance exhaust upgrade

• SS304 stainless steel construction for durability and corrosion resistance
• Direct OEM‑style fitment for a true plug‑and‑play installation
• Reduced backpressure for increased power and significantly more torque
• Lower thermal stress on the turbo for improved efficiency
• Enhanced exhaust flow for quicker turbo spool and better drivability
