Thanks for the replies.

I would rather keep the single 3" from the diff onwards as I don't want to buy new mufflers etc.

There are currently only a couple of photos of my ute on the Queensland Raceway site but that's it. I now have a digi camera so I will post some up when I can.

The exhaust has already been modified for more clearance but I would like more if possible. It's not a hanger issue just a big pipe under a low car issue hence the split pipe idea. I simply can't get anymore room with a 3" diameter pipe.
