Corsa Performance Exhausts, a TMG Performance Products company, offers a premium axle-back exhaust system for 2009-2011 ZR1 Corvettes. Featuring Corsa’s patented Reflective Sound Cancellation (RSC) technology, the ZR1 Exhaust System (part #14164) delivers a true high-performance sound on the throttle without the annoying drone at cruising speeds. Its straight-through 3.0-inch, nonrestrictive design and mandrel bends provide a 45 per cent increase in airflow versus stock. Plus, Corvette C6 ZR1 owners can expect a performance increase of 12-14 additional rear wheel horsepower and up to 15 lb.-ft of torque. Manufactured from military-grade 321 Stainless Steel, the ZR1 dual rear exit exhaust system boasts double wall, fully polished Twin 4-inch Pro Series Tips laser etched with the CORSA logo. Complete installation hardware and instructions are included with the exhaust system.
