I noticed your post, your close to me. there is a muffler shop in Burlington, NC. they've done several for me, and he does almost all of the high end stuff in this area. unfortunately, they are not able to do mandrel bends. but everything they do is top shelf!! its Alamance Muffler, on Mebane St, Burlington. I can get you a number if you'd like. or anyone else close by that would like top notch work.
