VRSF F97 X3M / F98 X4M Downpipes, S58 | 2020-2024

The VRSF downpipes replace the factory downpipes on the S58-powered F97 X3 M and F98 X4 M, including Competition models. Choose the catless track-limited race version or a high-flow catted version.

What It Does

The factory downpipes hold restrictive catalytic converters right behind the twin turbos. Replacing them cuts back pressure, so the turbos spool faster and the S58 pulls harder. VRSF measures about 30 whp and 35 wtq as a bolt-on and up to 60 whp and 100 wtq with a DME remap. The exhaust note also gets much more aggressive.

Materials and Construction

Rather than necking down near the turbos, the VRSF pipes use a smooth mandrel-bent design for more flow. They are hand made from 304 stainless steel tubing, TIG welded with smooth radius bends, and use CAD/CAM-optimized 304 stainless CNC flanges.
