RM Downpipe kit, BMW 135/335i(x) (N54 engine)

RM Motors upgraded downpipe offers an instant relief for N54 exhaust

In turbocharged engine the first metre of exhaust is the most critical. This should be one of the very first steps when tuning your engines performance, less backpressure, lower exhaust temperature and more flow.

For most of the BMW models we offer both de-catted versions and high-flow cats. Please check your local emission regulations, this product is not E-certified.

This kit is available with optional ceramic coating, to reduce the heat load towards your engine bay and transmission.

• Bolt-on fitment, both RHD and LHD models (catted only for LHD)
• Flow optimized design, CAD designed flanges
• TIG-welded 304 grade stainless steel.
• Manufacturer claims gains up to 25-30hp in tuned engine

Confirmed fitment for following models:
2007 – 2010 E90/E91/E92/E93 BMW 335i N54
