Red,
I took my old exhaust in to a shop (local) and had my guy bend new stuff which I installed at home. I didn't want to be welding out bends and flares. My truck doesn't drive yet. All new tubing, bends, clamps, mufflers, chrome tip cost $200. It was well worth it. The time it would take to build your own in (if you haven't done it before) my opinion negates the savings.
