VRSF Race Catless Downpipes for your F97 & F98 BMW X3M & X4M. These downpipes are the best bang for the buck mod available for your S58, with gains from 30 whp & 35 wtq as a direct bolt on. By eliminating the restrictive catalytic converters in the factory downpipes, back pressure is reduced significantly which results in faster spool, an increase in power & a more aggressive exhaust note.
Features:
- Adds up to 60 whp to the wheels & 100 wtq to the wheels when tuned.
- CAD/CAM optimized 304 grade stainless steel CNC flanges.
- Hand made from mandrel bent, tig welded 304 grade stainless steel.
- Smooth radius bends to decrease turbulence and increase flow.
- Fits RHD and LHD models with no modification necessary.
