VRSF 3″ Race (Catless) Downpipes for the S58 engine as found in the G80 M3 and G82/G83 M4. With their unique cast stainless steel v-band to pipe transition, these 3″ downpipes offer big power gains and perfect fitment.  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 competitor products, VRSF’s 3″ race downpipe feature a full 3″ design up to the last couple of inches of the pipe which allows an increase of flow. They are hand crafted from SS304 stainless steel and include a lifetime warranty. Grade 12 installation hardware is included with purchase.

Features:

• Gains of 22-27hp and 28-33lb ft to the wheels before tuning
• Hand-made from mandrel-bent, TIG-welded 3″ 304 grade stainless steel
• Smooth radius bends to decrease turbulence and increase flow
• Fits LHD and RHD, RWD and AWD models with no other modifications needed
• High quality grade 12 mounting hardware included
• VRSF Lifetime Warranty against defects and fitment

Please note that removal of emissions equipment is not MOT compliant and so these parts are for off-road use only.
