What can I say it's "Magnaflow, the best"!

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.
