BMW N55 downpipe F25 F26 2011–2018

Downpipe for BMW with the N55 engine — replaces the factory pipe right after the turbocharger. The larger diameter and smooth bends reduce exhaust restriction, so the turbo spools up faster and the engine responds more eagerly.

• BMW X3 35i / 35ix F25 (2011–2017)
• BMW X4 35i / 35ix F26 (2014–2018)

• Downpipe diameter: 3.5" (89 mm)
• Mid-pipe connection: 80 mm
