VRSF BMW 3" Catless Downpipes M3 & M4 (S55)


  • £499.04
    exc. VAT £415.87


At ML Performance, we are proud to introduce you to the 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 value downpipes available on the market 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.

Rather than necking down closer to the turbos like most downpipes on the market, the VRSF 3" catless downpipe feature a full 3" design up to the last couple of inches of the pipe which allows an increase of flow. The VRSF 3" downpipes are hand crafted from SS304 stainless steel and includes a VRSF lifetime warranty which includes fitment & defects. Grade 12 installation hardware are also included with the purchase.

VRSF also offer ceramic coating services on these utilising Cerakote High Temperature Ceramic coating, made to withstand temperatures up to 1800 °F. Please note that while VRSF do offer a lifetime warranty on the downpipes, VRSF only offer a 1 year warranty on the ceramic coating services due to the nature of the product. 



  • 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 neccessary.
  • High quality grade 12 mounting hardware included.
  • VRSF Lifetime Warranty against defects and fitment.
