VRSF Catless Downpipe for N55 F26 X4 M40i

The VRSF Upgraded Down Pipe for your F26 X4 M40i is THE best bang for the buck power mod available and it is available in either a race configuration or you can opt for our 200-cell high flow sport cat configuration. Back pressure is significantly reduced when eliminating the restrictive catalytic converter in the factory downpipe which results in faster spool, increased horsepower & a more aggressive exhaust note.

Every VRSF downpipe is constructed from mandrel-bent, SS304 grade stainless steel and our flanges are precision machined in order to ensure proper fitment every time. We also include a lifetime warranty as well as our “No Hassle” satisfaction guarantee (including fitment).

• Made from mandrel bent, tig welded 304 grade stainless steel.
• Smooth radius bends decrease turbulence and increase flow.
• 200 cell high-flow sport cat & race options available.
• Precision machined CNC flanges made from SS304.
• Gains from 20-25hp with tune.
• VRSF Lifetime Warranty
