We are proud to introduce our own catless & catted downpipes for your BMW S55 Engine!
This BMW S55 downpipe is available in both catless (race) & catted configurations.
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 full 3″ design up to the last couple of inches of the pipe which allows an increase of flow.
Our downpipes are handcrafted from mandrel-bent SS304 grade stainless steel and our CNC precision-machined flanges are also constructed from billet 304-grade stainless steel.
