2-1/2" dual exhaust with headers install.

Looks like the kit I got from Summit for my 73 Sport, except mine had mufflers included. Not sure about yours, but mine was designed for Hooker Super Comp headers. Instructions said that modification would be required for other header brands. Since I'm running Schumacher headers, and a 200-4R trans, I had to fab my connectors from the header back about 3 feet.
