    "I found the product easy to install, the only improvement that I could suggest is making all lengths of exhaust pipe so that they prefitt. I had to go to an exhaust shop to widen the pipe so that it would fit inside each other. Then cut slots so that it would tighten. Product sounds great and looks good. "

    "I replaced my Magnflow exhaust system with a Flowmaster. The Magnfow after several years became very loud. I contacted Magnflow 5 months ago for a free warranty replacement and they gave me the run around. So after repeated calls with no success I bought a Flowmaster. This system is great and my wife now rides in my Hummer again."

    "I love Magnaflow Cat-Back System. The Instruction I received were very easy to follow. Once installed, the new exhaust looks stock because the Hummer H3 comes custom with two cut outs that are fit for the new Dual system. Great sound too! I Love It!!!"
