Summit exhaust kit
I've got one on my 72 Valiant. If you're on a small budget like me I think it worked out great. The mufflers are cheap but aren't to bad. When I measured them they were really close to the same size as Flowmaster's. I have Hooker"s (dents and all) so they bolted up without to much trouble. If you can lift the car up level it really helps. I found out the hard way. Good Luck.
