S55 Ceramic coated VRSF 3″ High Flow Cast Stainless Steel Downpipes. We are proud to introduce our ceramic coated VRSF 3″ Race Downpipes for the S55 F80/F82/F87 M3, M4 and M2 Competition. 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.
