You went to 503 motoring? dude...get your butt to a specialty exhaust shop. Here we REALLY have NO need for all stainless bs. Sure it's cool...but my pipes are plain old aluminized and done locally too, been on the truck since 04 and dude, they still look new. My exhaust when i did it, ran me about $150 to hang(single tailpipe) and duals were like $200-220 to bend and hang up.
See what an exhaust shop will do for ya. Mulligans muffler in Sandy, OR is a great place to go to...Randy's a great guy to deal with. He's a pretty cool dude.
I would suggest Master Muffler(where I went), but i think they are out of business as of now. That's where I had mine done at. They had multiple locations throughout the Portland Metro Area.
