Anyone know of a good muffler shop?

I'm looking for a muffler shop that will do a mandrel-bent piece of (preferrably stainless) steel piping, 2.5" in diameter for my '06 WRX's midpipe. Unlike the '02-'05 cars, the midpipe is a single piece with slight bends, not two pieces like before. After a lot of searching, I found that Stromung sells the piece I'm looking for, but at $160.00. I'm hoping that a local shop could do it for less? This is what I'm talking about:



Anyone have a place they recommend?

 

I have a Bosal, looks the same as Stromung but without the cat.

 

Mainstream Performance does custom exhaust and the prices don't seem to be too bad. Hope that helps.
