69 Dart exhaust

Looking for a shop to fab up a set of custom tail pipes for my 73 Dart Swinger.
The car is mini tubbed to the rail and has a 3" spring relo kit, and 7.5 " backspaced rims.
Currently the exhaust exits in front of the rear wheels with spin tech mufflers(way to loud) .
Looking for a shop in the NJ NY Pa area. Any Suggestions.
