Replaced stock H3 exhaust

Reviewed By Mary T (MONETA, VA) Reviewed for a 2007 Hummer H3 —6/14/2018 10:08 PM

I loved how easy it was to install. I only had one issue with the tip touching the mudflap. Other than having to remove the mud flap on the driver side it looks awesome and sounds slightly more aggressive.

Hummer H3

Reviewed By Gregory B (Leavenworth, KS) Reviewed for a 2007 Hummer H3 —9/26/2008 9:04 AM

Purchased the magnaflow exhaust system inconjunction with the True Flow air intake system for a Hummer H3. I installed the air intake system myself. It was simple, just as the instructions described. I had the magnaflow exhaust system installed by a professional shop. It looks and sounds great. Not too loud. Just a little more depth to distinguish it from the stock system. I have noted a slight increase in fuel mileage since installing both systems. This was a primary motivation for purchasing both systems. Hopefully, fuel mileage numbers will improve after more driving and fillups. Overall, I am quite please with quality, look and sound of both systems.
