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.

Muffler was quality in appearence and sounds just as I thought it would not to loud but a nice throaty growl, in fact now I wish id bought the whole package for a true dual exhaust system to give it real breathing ability, my muffler tech says it cant be done on my vehicle, im sure all I need is another cat converter xpipe muffler and tail pipe and it would work, may need to run tailpipes on passenger side because of spare tire blocking pipes(no room to pass between spare and leaf springs),usay?
