Exhaust

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® (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.

Important Notice relating to US Domestic Market Trucks & Pickups

Many US-market trucks and pickups are available in multiple cab and bed-length configurations (e.g., Single Cab, Extended Cab, Double/Crew Cab, CrewMax, 5.5ft/6.5ft/8ft beds, etc.). Exhaust system fitment can vary between these chassis versions.

Where available, we list all compatible vehicles, cab types, and bed lengths in the product description. However, depending on your exact configuration, some systems may require optional extension/mid-pipes or minor modification for correct fitment.

Because of these variations, please carefully check your cab configuration and bed length before purchasing. If you are unsure, or if your vehicle has been modified, please reach out to a StreetFX agent.
