Overall nice dual tip exaust for 2007 H3 Hummer

was louder than I liked so I replaced the muffler with a GM product which reduced down the load tone. overall I had a pickup of speed which was a plus.

I purchased the single side swept system about a month ago, I purchased this with the Black Metal Mulisha tip put the system on my h3 as soon as it arrived, installation was pretty easy but I recommended having an extra set of hands I installed it on my own took me about 3 hrs, removing the oem system was the hardest part, as for sound its not too loud but it gives it a nice aggressive exhaust note and dont worry it sounds nice, I was a bit worried that it would sound like a Honda Civic ......

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.
