Dynomax super turbo muffler size

How about the Summit Racing kit? It comes with Summit brand mufflers. Has anyone used the Summit kit? How does it compare to Dynomax?

I figure that even if I go with the Dynomax muffflers, I would have to buy the Summit kit to get the tail pipes.

I have not found any A body 2 1/2 mandrel bent tail pipes beside the Summit kit.
