Enhance performance and retain road legality with these Ceramic Coated Sports Cat Downpipes for the BMW S58 engine. Designed for the G80/G81 M3, G82/G83 M4, and G87 M2, these downpipes feature a high-flow 200-cell catalytic converter that significantly improves exhaust flow while maintaining emissions compliance in many regions. Crafted from premium stainless steel and finished in a heat-resistant ceramic coating, these downpipes reduce turbo lag, improve throttle response, and produce a deeper, more aggressive exhaust note—all while controlling underbonnet temperatures.
