i have a friend who can probably mandrel bend some 3 in pipe for me for an exhaust. is there anywhere to get the bends needed without having a 1g exhaust to look at?

I'm assuming you mean a diagram? I haven't seen one around but I think it would be a pita. It would probably be much easier to find someone that has a system to look at.

thats what i figured but was just wondering. thanks.

no diagram, but go to www.roadraceengineering.com and look at the pictures of their downpipes, might give you an idea of what you need.

If you need the catback design, just look for pictures of the N1 catback, will give you an idea of what it should look like.
