The VRSF N55 Downpipe Upgrade is specifically designed for 2012–2018 BMW models, including the M135i, M235i, M2, 335i, and 435i. This high-performance downpipe offers a catless (race) version that eliminates the restrictive catalytic converter found in the factory downpipe. As a result, it reduces back pressure, enables faster spooling, increases power output, and delivers a more aggressive exhaust note.
Constructed from mandrel-bent SS304 grade stainless steel, the VRSF N55 catless downpipe ensures durability and optimal flow. The CNC precision-machined flanges, made from billet 304 grade stainless steel, contribute to smooth airflow and reduced turbulence.
Fitment details vary based on production dates:
M135i and 335i models produced up to 07/13 require the 3.5" version of this downpipe.
M135i and 335i models produced after 07/13 require the 4" version.
M235i and 435i models also require the 4" version.
