This is my problem. I want to install some kind of cat back system. Right now I'm looking at magnaflow and flowmaster, but I am open to others. Situation: I want to install this myself since It looks pretty easy. I've read I have to cut the old oem system out, I do have a lift that will bring the truck over my head, but It's in the back of my hangar. This means I could slide it out potentially (I don't want to move any airplanes right now, its too cold outside I think I might lose $'s from the heat lost) I am going to weld them eventually, but when I can get the truck into my building. All I want is some nice tone and no to little drone, but all the while having a ballsy sound when I get on it. I'm thinking a single in dual out the back configuration. Also I don't know if weather makes a difference. I live in Fairbanks Alaska and it can get cold, there is snow. I don't think the roads are salted. Anything is helpful. 2006 Chevy Silverado Z71 Crew Cab 5.3L Cat back would be the first non stock thing. Except for deck and home made front moose light bar.
