Rvng E9X N55 Downpipe
Rvng Upgraded N55 Downpipe
For your BMW 135i & 335i/xi (N55 Engine)
The Rvng 3.5″ Downpipe Upgrade is the best bang for your buck modification available for your N55 135i and 335i/xi. By eliminating the restrictive catalytic converter found in the factory downpipe, back pressure is significantly reduced, resulting in faster turbo spool, increased power, and a more aggressive exhaust note. The downpipe features a unique CFD-optimized cast merge collector, ensuring the smoothest turbo-to-midpipe transition.
Every Rvng downpipe is handcrafted from TIG-welded, mandrel-bent 304 grade stainless steel. High-quality replacement hardware and mid-pipe gaskets are included, though we highly recommend purchasing the optional turbo clamp and gaskets if your vehicle has more than 60k miles.
