I'm looking for a shop to do some custom exhaust work on my B8 S4, specifically a shop that can TIG weld. I've called up a handful of places and no one seems to have the capability. Does anyone know a shop that can do this or am I SOL?

The configuration I'm going for is replacement of the baby resonators with the Magnaflow 11386 (2.5" diameter) and straight pipe 2.5" (vs stock 2.25") all the way through to the mufflers which will be replaced with some kind of valved mufflers.
