call heman or superman!


but no honestly, thats not really something you can do at home by yourself.
you need either a mandrel bending machine, or a crush-bending machine to bend exhaust piping, neither of which are cheap.
if its in any shape to be drivable, i'd say drive it down to your local exhaust shop and let them help you.

You can try the OLD OLD school way will it with sand cap off all the ends, use a c clamp hold down one eng then pull the other the way you need it to. Im sure there is a EZ er way to do it tho.

IF you can get a torch then that should do it just go slow and maybe use a pry bar in the other end to help.

just have a good backup plan. If you don't get it hot enough, the metal will rip for sure and/or won't be shaped properly. That is the beauty of the mandrel and crush bending methods...they distribute the pressure evenly and keep the proper circular shape. As usual I think twok will end up being right on this one.
