The CORSA Performance Silverado ZR2 and Sierra AT4X catback exhaust offering was designed for one reason: To give GM's full-size offroader the voice it deserves. A noticeably loud, deep and aggressive exhaust note balanced with a completely drone-free driving experience courtesy of CORSA's best-in-class RSC(R) (Reflective Sound Cancellation) No Drone Technology. The CORSA Performance custom tuned exhaust system unleashes 25 decibels of sound and offers a straight-through design that elmiinates restrictions allowing the system to easily outflow the stock exhaust by up to 47% freeing up horsepower and torque. CORSA Performance catback exhaust systems are meticulously constructed from 304 Stainless Steel, engineered to endure a lifetime of use and withstand the rigors of off-road adventures.
