Need help buying exhaust!!!!

I have the Summit 2.5 inch exhaust on my 1972 Duster 340. I think they are really nice. Had to cut out about 4-6 inched out of the middle of the front passenger pipe, but that did not sway my opinion on it. Sure, you could spend $500.00 on a custom bent exhaust and get a nice set up (or not) depending on the skill of the guy bending the pipes.
Now for the bad news. They probably won't fit on the rear of your car as the tail pipes mount right in the middle of the rear frame rail.
