We are proud to introduce our VRSF Race 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 and gains of up to 60 whp and 100 wtq when paired with the the Stage 2 BM3 91 octane map. 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. We offer these downpipes in both race configurations as well as a 200 cell race cat configuration.
Rather than necking down closer to the turbos like most of our competitors, our race downpipes feature a smooth mandrel bent design which offers a significant increase in flow. Our downpipes are hand crafted from SS304 stainless steel and include a lifetime warranty & our “No Hassle” satisfaction guarantee which includes fitment & defects.
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.
- VRSF Lifetime Warranty against defects and fitment for race version, 1 year limited warranty on catted..
