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.

Awesome Exhaust

Reviewed By Dave D (Frisco, TX) Reviewed for a 2007 Hummer H3 —7/23/2007 6:40 AM

Just purchased 07 Hummer H3. Couldn't stand the air intake being louder then the exhaust. Bought the cat-back system. Installation was exactly as diagramed and was a breeze. Has a quiet mellow tone now that sounds great. The dual exhaust tips look awesome too.
