Corsa 21-25 Chevrolet Suburban/GMC Yukon XL 5.3L 4WD Dual Rear 3in - 2.75in CatBack DW 4in Pol Tips

When you open this box, you're getting a complete cat-back exhaust system from CORSA Performance, designed specifically for your 2021-2025 Chevrolet Suburban or GMC Yukon XL with the 5.3L 4WD engine. This kit includes the main exhaust piping, mufflers, and a pair of polished stainless steel dual-wall tips, all made from durable 304 stainless steel. It's engineered to replace your factory exhaust from the catalytic converter back, making it a straightforward bolt-on installation with no cutting required.

CORSA's signature Reflective Sound Cancellation (RSC) technology is at the heart of this system. It uses acoustic engineering to eliminate that annoying drone inside the cabin at cruising speeds, while still letting you hear a deep, aggressive rumble when you step on the gas. This isn't just about sound, though. The system features a straight-through design with mandrel-bent tubing, which helps maximize airflow. CORSA claims this can unlock up to 20 percent additional horsepower and torque, and also improve fuel economy. The Sport sound level is their most popular choice for GM SUVs, offering a noticeable but not overwhelming exhaust note.

Installation is designed to be a simple bolt-on process, typically taking about an hour, so you can get back on the road quickly. The twin 4-inch Pro Series tips are polished to a mirror finish, adding a sharp look to the rear of your SUV. This system is built to last with its 304 stainless steel construction and comes with a limited lifetime warranty.
