3.5"-3.0" Cat-Back Exhaust with Dual Mode Active Exhaust

Corsa 3.5" Mid-Pipe, Dual Rear Exit with Twin 4.5" Tips

The S58 twin-turbo inline-six is one of the finest engines BMW has ever built, and the Corsa Performance Active cat-back exhaust for the G80 M3 and G82/G83 M4 finally gives it the voice it deserves. With the valves open, it’s 17 dB louder than stock (SAE-measured) and flows 31% better, delivering a sharp climb to redline, a deep bark at wide-open throttle, and crackle on overrun. Because it retains the OEM exhaust valves, you stay in control. Your factory drive modes and exhaust button work exactly as BMW intended, so you can keep things subdued for early mornings and quiet neighborhoods, then open it up when the road calls. Corsa’s Reflective Sound Cancellation (RSC) technology cancels the frequencies that cause cabin drone, so all that aggression never turns into fatigue on the highway. The system is built around a single-run 3.5" mandrel-bent midpipe for a clean, free-flowing path, and its sound was tuned with downpipes in mind, so it stays dialed in as your build grows. Run it straight through for the rawest, most aggressive note, or add the optional resonator for a more refined tone. Every system is constructed from 304 stainless steel for long-term durability and corrosion resistance, and finished with quad 4.5" tips in your choice of Polished Slash Cut, Black PVD Slash Cut, Carbon Fiber Polished, or Carbon Fiber Black. The carbon fiber options feature real carbon sleeves over stainless tips for a race-inspired look that pairs perfectly with M carbon trim. Installation is a direct bolt-on using factory hangers, with no cutting or modification required, and every system is backed by the Corsa Limited Lifetime Warranty. Stealth when you want it, savage when you need it, and drone-free the whole way.
