VRSF 3″ High Flow Stainless Steel Downpipes

For your 2020+ BMW M3, M4 with the S58 Engine

We are proud to introduce our VRSF 3″ Race Downpipes for the S58 G80/G82/G83 M3, M4. These 3″ downpipes are the best bang for the buck mod available for your S58, with gains from 27hp & 33tq when tuned. 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.

Rather than necking down closer to the turbos like most of our competitors, our 3″ race downpipe feature a 3″ design with a gradual neck down to match the factory midpipes which allows an increase of flow. Our 3″ downpipes are hand crafted from SS304 stainless steel and include a lifetime warranty & our “No Hassle” satisfaction guarantee which includes fitment & defects.

Features:

• Adds 22-27 HP & 28-33 TQ to the wheels.

• Hand made from mandrel bent, tig welded 3″ 304 grade stainless steel.

• Smooth radius bends to decrease turbulence and increase flow.

• Fits RHD and LHD models with no modification necessary.

• High quality grade 12 mounting hardware included.

• VRSF Lifetime Warranty against defects and fitment.
