DESCRIPTION
We are proud to introduce our VRSF racing downpipes for your BMW X3M and X4M F97 and F98. These downpipes offer the best value available for your S58, delivering gains of 30 Whp and 35 Wtq as a direct bolt-on and up to 60 Whp and 100 Wtq when paired with the BM3 91 Stage 2 octane map. By eliminating the restrictive catalytic converters in the factory downpipes, backpressure is significantly reduced, resulting in faster spool-up, increased power, and a more aggressive exhaust note. We offer these downpipes in both racing configurations and a 200-cell racing catalytic converter setup.
Rather than approaching turbochargers like most of our competitors, our racing downpipes feature a smooth mandrel-bent design that provides a significant increase in flow. Our downpipes are handcrafted from SS304 stainless steel and include a lifetime warranty and our hassle-free satisfaction guarantee, which covers installation and defects.
We can assemble and adjust the parts in our workshop. Feel free to contact us by email if needed: RpK.MotorSport@gmail.com
