Corsa 2021-25 Chevrolet Suburban 5.3L 4WD Single Side 3in Sport Cat-Back 4in DW Round Black PVD Tip

The 3-inch diameter, 304 stainless steel tubing in this CORSA cat-back system is mandrel-bent for maximum airflow, which is key for improving both performance and fuel economy. This system is specifically tuned for the 5.3L engine in your 2021-2025 Chevrolet Suburban, aiming to unlock up to 20 percent more horsepower and torque based on dyno testing.

What really sets CORSA apart is their patented Reflective Sound Cancellation (RSC) Technology. Acoustic engineers use this to create a deep, aggressive rumble when you step on the gas, but it eliminates that annoying drone inside the cabin during cruising speeds. You get the sound you want when you want it, and quiet comfort when you don't. The system features a single-side exit with twin 4-inch diameter, dual-wall round black PVD tips for a sharp look.

Installation is designed to be straightforward, with a bolt-on design that requires no cutting. Everything you need for installation is included, and it's made in the USA from high-grade 304 stainless steel for long-term durability. This is CORSA's popular 'Sport' sound level, offering a noticeable improvement over stock without being overly aggressive for daily driving.
