Yeah, this is true. Before I decided to weld my exhaust myself, I looked around for some shops to do it for me, and didn't find much. My advice would be to avoid just exhaust/muffler shops, their work is generally cheapest and they usually don't work with stainless. Every big city has more than one real custom-fab performance shop though. Check a shop like this' site for examples of their work. If they do engine swaps and such, they will be able to tig weld stainless no problem.

It is a catback, all mandrel-bent 2.5 inch 304 stainless, underaxle, with a large Hushpower II res and Aero SS mufflers very similar to the Borla XR1, with quad tips. It cost $1200 parts and labor and took the shop in Pasadena, MD 10 hours to design (using CAD) build and install/tune. I've had it 5 years now and it still looks and sounds brand new.
Thank you sir.
Nice setup! Looks great and I'm sure it sounds great. A setup like yours ought to silence the many custom exhaust haters on this site.
