The MagnaFlow Chevrolet Avalanche Street Series Cat-Back Performance Exhaust System brings out the personality of your 5.3L Chevrolet Avalanche with our signature resonant, powerful engine tone and dyno-proven performance. Thanks to its fast-flowing, mandrel bent 3in. main piping and 1 Straight-Through mufflers ending in a Single Passenger Side Rear exit with 5.5in. Polished Welded-On Double Wall Straight Cut Rolled Edge tips, this Chevrolet Avalanche exhaust kit has the performance chops to match its sporty sound and appearance. Upgrade your ride to the next level with an exhaust that has the pipes to put other Chevrolet Avalanche's to shame. With this system your vehicle will be producing Moderate exterior and Mild interior sound levels while leaving other cars and trucks feeling envious at every stoplight. Exhaust kit 16721 features a cat-back layout that replaces your ride's stock exhaust components from near the catalytic converter on back.

Penelope ★★★★★

Spent the weekend installing this on my 5.3L Avalanche and the deep rumble at idle is exactly what I was hoping for. The drone on the highway is minimal, so it stays comfortable for daily driving.

Sofia B. ★★★★★

The install was straightforward and the deep, resonant tone from my 5.3L Avalanche is exactly what I was hoping for. The system feels solid and the engine note really turns heads without being obnoxious.

Sophia ★★★★★

The 409 stainless steel construction feels solid and should hold up well through our salty winters. After installing on my Avalanche, the deep idle tone is exactly what I wanted without being obnoxious on the highway.
