High-Flow VRSF 3.5″ Cast Stainless Steel Downpipes – Precision-Fit for BMW X3 M (F97) and X4 M (F98)

Description

We are proud to introduce our Racing Downpipes for your F97 & F98 BMW X3M & X4M. These stainless steel tube down pipes 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 a DME remap. By replacing the restrictive catalytic converter in the factory downpipes with our high flow, 200 cell catalytic converter, back pressure is significantly reduced which results in faster spool, an increase in power & a more aggressive exhaust note.

ather than necking down closer to the turbos like most of our competitors, our downpipes feature a smooth mandrel bent design which offers a significant increase in flow. These are hand crafted from 304 grade stainless steel tubing and include a lifetime warranty..

• Adds up to 60 whp to the wheels & 100 wtq to the wheels when tuned
