For $339, you really can't beat the Flowmaster 17139 kit for the '69. It's 2.5" tubes all the way back with an H-Pipe to help equalize exhaust gases, and it includes a set of Flowmaster Delta-40 mufflers.

And it includes EVERYTHING you need; hangers, clamps, screws, bolts...nothing is left out.

Here are a few pics
