I have a Magnaflow 5" on mine that I installed. In all is a fairly easy install. I did mine in the driveway, if one had a lift it probably would be very simple. I also have a B&W turnover hitch setup which was the only bit of a problem with clearances. Because of the crossmember on the hitch it was very close but with a little extrea care works fine. All the hangers and pipes are good quality and fit well. It was harder to get the old off than put the new on. I would recommend a sawzall and not worry about saving anything. I tried to get the downpipe and cat off in one pice in case I might have to reinstall for some unknown reason, doesn't work out , had to cut in front of the the cat to get it off. Be sure to tighten the clamps very well for if you don't thet work loose.
