I'm going to be changing the exhaust on my car. Currently it exits before the rear wheel, passenger side with a super trapp. I was wondering how many people go over the axle, how many under, and with one pipe to the muffler or two?

I have a fuel cell in the back and it looks like it would be difficult to run pipes over the rear axle and not hit the thing. I could fix this by moving the cell more driver side, but that seems like a lot of weight on one side of the car (driver + fuel). I know I've seen some that just run it straight back under the axle. Does that cause some probs jacking the car up? I'd hate to damage the headers by yanking around on the exhaust.

Thanks folks!
