Gibson 07-12 Chevrolet Avalanche LS 5.3L 2.25in Cat-Back Dual Split Exhaust - Aluminized

If you're looking to give your 2007-2014 Chevrolet Suburban 1500 a more aggressive sound and a bolder look, this Gibson cat-back exhaust system is a solid choice. Designed to replace your factory exhaust from the catalytic converter back, this system features a dual split rear exit with polished stainless steel slash-cut tips that look great peeking out from under the bumper. It's built to reduce backpressure, which can lead to a bit more torque and horsepower.

The heart of this system is Gibson's Superflow muffler, which uses baffles and chambers instead of internal packing. This design helps minimize interior drone while still giving you that satisfying, throaty exhaust note, especially when you're on the throttle or towing. The tubing itself is aluminized steel, bent using a mandrel process to ensure consistent diameter throughout, which helps maintain smooth exhaust flow. Installation is designed to be straightforward, with a bolt-on setup that typically doesn't require any welding, making it a manageable project for many DIYers.

This Gibson cat-back system is designed to work with most factory bumpers, roll pans, and trailer hitches, so you shouldn't have to worry about clearance issues. It's backed by a lifetime limited warranty from Gibson, giving you peace of mind with your investment. While it's designed for an aggressive sound, the baffled muffler aims to keep it from being overwhelming inside the cabin during normal driving.
