The MagnaFlow Hummer H3 Street Series Cat-Back Performance Exhaust System brings out the personality of your 3.5L, 3.7L Hummer H3 with our signature resonant, powerful engine tone and dyno-proven performance. Thanks to its fast-flowing, mandrel bent 2.5in. main piping and 2 Straight-Through mufflers ending in a Dual Split Rear exit with 3.5in. Polished Welded-On Double Wall Angle Cut Folded Edge tips, this Hummer H3 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 Hummer H3'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 16630 features a cat-back layout that replaces your ride's stock exhaust components from near the catalytic converter on back.

Ella Q. ★★★★★

The sound is deep and aggressive without being obnoxious on the highway—exactly what I wanted for my H3. Installation was straightforward with all the hardware included.

Madison ★★★★★

I finally got tired of the stock exhaust sound, and this cat-back system woke up the H3's 3.7L nicely—the deep tone when accelerating through 2500 RPM is exactly what I wanted. Installation was straightforward with the mandrel-bent pipes lining up well, and it feels like there's a bit more throttle

Sophia N. ★★★★★

The deep, throaty rumble at startup was exactly what I was hoping for, and it really woke up the truck's personality without being obnoxious on the highway. Installation was straightforward with all the necessary hardware included, and the dyno-proven performance gain is a nice bonus.
