BRM N55 Stainless Steel Down Pipe - Catless
We are proud to introduce the BR Motorsport 4″ ‘RACE’ catless downpipe for your N55 M135i, M235i, M2, 335i & 435i F20/F21/F2 variants. This 4″ downpipe is the best value modification available. By eliminating the restrictive catalytic converter in the factory downpipe, back pressure is reduced significantly which results in faster spool, an increase in power & a more aggressive exhaust note.
This downpipe is a simple to fit upgrade that also allows for stage 2+.
The BR Motorsport catless downpipe features a full 4″ stainless steel design as well as a CNC 304 grade stainless steel flange that offers a smooth transition from the turbo to the mid pipes. All BR Motorsport downpipes are hand crafted from SS304 grade stainless steel.
- Made from hand crafted, tig welded 304 grade stainless steel.
- Smooth radius bends to decrease turbulence and increase flow.
- CNC Machined flanges and laser cut brackets 304SS
- Gains from 15-20hp with tune
- 4" diameter pipework
