3" Cast Stainless Steel Catless Downpipes by VR Speed
We are proud to introduce our VRSF 3" Catless Downpipes for the S55 F80/F82 M3 & M4 which are one of the only downpipes to feature a cast stainless steel v-band to pipe transition. These 3" downpipes are the best bang for the buck mod available for your S55, with gains from 25hp & 30tq 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.
Adds 20-25 HP to the wheels & 25-30 TQ to the wheels.
CAD/CAM designed cast flange for seamless flange to pipe transition.
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.
