High-Flow Cat3.0T Downpipes for 2019-2022 BMW X3M/X4M (F97/F98) S58

Description
We are proud to introduce our Downpipes for your F97 & F98 BMW X3M & X4M. These downpipes are the best bang for the buck mod available for your S58, with gains from 30 whp & 35 wtq as a direct bolt on and gains of up to 60 whp and 100 wtq when paired with the the Stage 2 BM3 91 octane map. 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. We offer these downpipes in both race configurations as well as a 200 cell race cat configuration.
Rather than necking down closer to the turbos like most of our competitors, our race downpipes feature a smooth mandrel bent design which offers a significant increase in flow. Our downpipes are hand crafted from SS304 stainless steel .Please note, both primary and secondary downpipes are included.

Feature
