70 Duster Stock Replacement System - any recommendations where to buy?

Dart guy, Joe has worked with me on the VOE/DCE muffler (see it on his website?) and in turn, he has helped me tremendously by making me some 70-71 Duster noise reduction tailpipes, some 69 340 Cuda pipes and a full system for a 71 Satellite Sebring. His tailpipes are shaped correctly and fit exactly like the originals I still have in the garage even though I had him make them in 2.5".

Joe is great guy and his company goes to great lengths to make things right. He has all the right jigs and books and patterns to do it correctly and he can find you the original (aftermarket) hangers too. :):)

He is also very good at creating nice sounding mufflers that look and fit right.
