Where to get pre bent exhaust pipes and any suggestions on how to swage them to fit over mufflers?

As weird as it sounds, I've considered welding in the 68-76 gas tank strap mount since I do have a parts car....

Damn that looks too nice to be demoted to "parts car". Where the guy at that was looking for everything to restore a rotted out 71 demon/duster? It was somewhere on here within the last 3-4 days
