Gibson Exhaust Systems Reviews


good exhaust for an H3

Reviewed By John M (Bloomfield Hills, MI) Reviewed for a 2007 Hummer H3 —1/29/2011 7:48 AM

I have had many exhaust systems on several cars. The Gibson is giving good performance with just the right exhaust tone. Also sounds good inside no loud reverb sound like some other systems. Would buy again from gibson.

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.
