Corsa Xtreme Valved Exhaust Systems
Crafted with precision and power in mind, Corsa Xtreme valved exhaust systems boast premium 304 stainless steel construction, Corsa-designed valves, double Helixx X-pipe, and custom-tuned mufflers tailored to the specific engine. Seamlessly integrating with the OEM Active Exhaust functionality, these precision acoustic tuned Xtreme systems unleash over 8+ decibels beyond the OEM exhaust with the valves open, delivering thunderous exhaust notes at your command. They capture attention during cold starts and heavy acceleration while ensuring a quiet, drone-free cabin during cruising, all thanks to Corsa's pioneering No Drone RSC technology.
Designed with a straight-through muffler construction, Corsa's exhaust increases flow by nearly 20 percent, enabling drivers to optimize the benefits of any performance modification. Elevating the aesthetic appeal, these system features striking 4.5 in. dual-wall stainless steel exhaust tips available in slash cut or straight cut in polished or black PVD finishes. Choose the packaged desired for your vehicle.
