BMW G80 M3 G82 M4 G87 M2 S58 200-Cell Race Downpipes

The IRL MaxFlow 200 Cell Race Downpipes unleash the BMW S58 with a MaxFlow design and high-flow 200-cell metallic catalytic converters, cutting exhaust restriction so the turbochargers spool faster.

Why you need it

Unlike downpipes that neck down and create turbulence, the MaxFlow design keeps exhaust flow smooth. That means quicker turbo response, more power through the RPM range and a deeper, more aggressive exhaust note with enhanced turbo sound.
