We are proud to introduce the BRM Performance RACE catless downpipes for your BMW F90 M5 4.0 twin turbo engine variant. This 3" downpipe is the best value modification available. By eliminating the restrictive catalytic converter in the factory downpipe, back pressure is reduced significantly which results in faster spool, an increase in power & a more aggressive exhaust note. This downpipe is a simple to fit upgrade that also allows for stage 2+.
The BR Motorsport catless downpipe features a 3" out of the turbo flange into a full 3" downpipes and connecting pipes, stainless steel design as well as a CNC 304 grade stainless steel flange that offers a smooth transition from the turbo to the mid pipe. All BR Motorsport downpipes are hand crafted from SS304 grade stainless steel.
