When I first thought about going duals, I called around to the local muffler shops and they told me it couldn't be done.

Then I called a Ford dealer and they recommended a shop that dealt with their conversions. I didn't take to that shop because they wanted me to leave my Mustang out in their very close spaced parking lot for 3 DAYS.....I said NOT!
I ended up taking it to a Transmission shop that builds Ford Racing cars. It was the first time they have ever done that kind of conversion, but so far no rattles or drones......looking for wood to knock on!
