I purchased the Gibson extreme Dual exhaust and love it. It took me and a friend about 3 1/2 hours to install at a shop and I have no experience with exhaust systems and his knowledge was limited to cars. But with the instructions and and simple bolt-on installation it was easy. The truck sounds awesome at idle and acceleration and then quiets off when cruising. I would definitely rate this a 10! and having shopped around for a while autoanything seems to have the best prices by far. I havent done to much highway driving since I put my system on but have noticed about a 2 mpg increase for city driving so far. This is a must get

Awesome exhaust system for the price. Love the roaring sound that is coming out of the exhaust pipes. It's sound a lot better than my previous exhaust I owned in recent years.

I have a 2008 dodge ram 1500 with a 5.7 hemi. The exhaust sounds awesome, was very easy to install. I have the extreme that exits behind the tires, the only problem was the left side rear hanger seems a little crappy, not too big a deal, the pipe just hangs a little close to the spare tire. It may take you a little to get the pipes to look even. I have a k & n 77 series cold air intake and i was getting around 15.1 for mileage with stock exhaust, now with the exhaust and cold air I get like 14.9. Not too much of a difference. I havent taken it on any long highway trips. Probally would have went with the rear exits though.
