Make sure the shop has a mandrel pipe bender or walk away. The resonators are not in a straight line like many other cars. Most shops do not have the equipment. They will just weld together prebent pieces which is not exactly the proper way to do leading to unsubstantial but still turbulence.
Welding a stainless steel x-pipe is pointless. Stock piping is anodized mild steel which (anodized aluminum) will burn off at the welds. Those areas are going to be the ones to rust the most.

The local guys here doesn't have a mandrel pipe bender so I walked away and ordered the Dinan D660-0080 - High Flow 3" Stainless Steel Pipe. Double the price of the custom work but I believe I'll be happier in the end. Plus I could always resell the Dinan pipe down the rode.
