VRSF F90 M5 / F92 M8 Race Downpipes, S63 | 2018-2025

The VRSF race downpipes for the F90 M5 and F91, F92 and F93 M8 replace the factory downpipes on the S63 twin-turbo V8, including Competition models. The factory system uses primary and secondary downpipes with four catalytic converters in total, and VRSF lets you replace the primaries, the secondaries or both.

What It Does

Each set of factory downpipes carries converters that restrict flow behind the turbos. Replacing them cuts back pressure, so the turbos spool faster and the V8 pulls even harder. With both sets replaced and a tune, VRSF measures up to 112 hp and 130 lb-ft at the wheels. If you buy only one set, you can keep your factory or aftermarket pipes on the other side.

Materials and Construction

The pipes use a smooth mandrel-bent design rather than necking down near the turbos. They are hand made from 304 stainless steel, TIG welded with smooth radius bends, and use CAD/CAM-optimized CNC flanges. A heat shield wrap is available on every option.
