S63 2011 – 2018 BMW M5 & M6 3″ Stainless Steel Racing Downpipes

3″ Race Downpipes for the S63 F10/F12 M5 & M6 which feature a CNC stainless steel v-band to pipe transition. These 3″ downpipes are the best bang for the buck mod available for your S63, with gains from 50hp & 60tq when tuned. By eliminating the restrictive catalytic converters in the factory downpipes, backpressure 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 a greater increase in flow. Our 3″ downpipes are hand crafted from SS304 stainless steel Features: Adds 50-55 HP to the wheels & 60-65 TQ to the wheels. CAD/CAM designed CNC flange. Hand made from mandrel bent, tig welded 3″ 304 grade stainless steel. Smooth radius bends to decrease turbulence and increase flow. Fits RHD and LHD models with no modification necessary.
