VRSF Downpipe 4.5″ Cat/Decat BMW B58 140i / 240i / 340i / 440i / 540i
Back pressure is significantly reduced by eliminating the restrictive catalytic converter in the factory downpipe with our decat downpipe or high flow 200 cell race cat downpipe which results in faster spool, an increase in power & a more aggressive exhaust note. Our downpipe features a full 4.5″ 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 VRSF downpipes are hand crafted from SS304 grade stainless steel and include a lifetime warranty as well as our “No Hassle” satisfaction guarantee (includes fitment).
- Made from hand crafted, tig welded 4.5″ 304 grade stainless steel.

- Smooth radius bends to decrease turbulence and increase flow.
- Fits the stock catback as well as all aftermarket catbacks.
