I wouldn't suggest you let ANY shops do any exhaust work. From my experience they are pretty useless unless they have a mandrel bender that can handle stainless steel piping and an actual WELDER working there. I made the mistake of having a shop make me a downpipe, they said aluminized steel would be best(i said i wanted stainless, they refused

) The bends were mediocre at best and the weld job was so HORRIBLE i actually walked up to the person welding and their manager and told them to allow me to weld it (they weren't happy, lol). Then they proceeded to charge me $200 for it. So i made sure to let them know i would be spreading the word about their handy work.
Maybe its just the shops ive been to but the people are lazy, inexperienced and overcharge to the max. Or maybe my standards are too high? I just expected them to fab me a downpipe that wouldn't leak and wasn't welded in the same place 5 times to cover a single seam. Is that too much to ask? (They failed too.) Come to think of it when i had my tires put on and alignment done, they underinflated my tires and took my celica for a joyride.
Undecided, If anything i would suggest you map out the way you want your exhaust system to be mounted. Buy the exhaust tubing you need, cut and do a mock fit up. Then bring it to a friend that has a welder and have them weld it up. It will be much cheaper that way if your only spending money on the parts and giving a friend some cash for the work. You can buy stainless or aluminized U-bends, J-bends, UJ- bends, 45deg, 60deg and 90deg bends and straight piping online. And if you can't find anyone, and you're willing to drive to appleton on a weekend, let me know before hand and im sure i can weld it for you. I have a Miller MIG welder i used to cover up the shops welds.
Right now i can't work on mine so i might as well help others anyway i can.
Btw, There are quite a few members that use the "ebay" header and have great success with them. No need to spend $180 on a $100 header unless its for preference cause in the end unless specified, they are all stainless.
Hope this helps,
