Performance Curve Cat-Back Dual Exhaust Kit For 2009-2014 Chevy Avalanche, Suburban, GMC Yukon XL – 5.3L With Aggressive Two-Chamber Muffler & Black Tips

Ready to give your 2009–2014 Avalanche, Suburban, or Yukon XL a serious upgrade in sound and style?

This Performance Curve cat-back exhaust kit is built for the 5.3L engine and comes with everything you need: mandrel-bent aluminized pipes, a two-chamber FlowSound muffler for that deep, aggressive tone, and sleek 4-inch black rolled-angle tips.

Exits behind both rear tires for a clean, balanced look.

Kit includes all clamps and hangers—clamp-on design makes install straightforward, though pro installation is always a smart move.

Fits 1/2 ton chassis and might need minor tweaks depending on your setup.

If you're after Flowmaster 817548 vibes without the premium price, this one's a solid pick.
