Upgrade your BMW 135i, 335i, or 435i with our high-quality stainless steel downpipe, designed for N55 single turbo engines. This aftermarket OEM replacement is intended for off-road, race/competition use only and will not fit BMW 135i & 335i built before August 2013 or N54 twin turbo engines.

Our 100% brand new downpipe is made of stainless steel and TIG welded for maximum durability. It features a 4" V-band downpipe diameter tapered design to increase velocity and gain 15HP, while eliminating the OEM catalytic converter for maximum exhaust flow.

This direct bolt-on downpipe fits all factory O2 sensors and comes with 2 x O2 sensor bung ports, exactly the same as the picture shown. Upgrade your BMW 135i, 335i, or 435i today with this high-quality downpipe for improved performance and sound.
