I haven't looked at the YJ exhaust for a while but I know the TJ exhaust crosses over to the passenger side and exits behind the passenger rear tire.

I don't know about yours, but that won't work for my '83 CJ. The CJ exhaust goes straight back... why not build your own or have one custom built.
Vibration? Bump steer? Wandering? Read the article (sticky) on Steering, suspension, and driveline.

The driveshaft being on the passenger side kind of forces you to run it straight back down the driver side. I think you would have a hard time snaking it over to the passenger side. I agree with gojeepin, have one custom built.

I bought the piece of pipe that comes off the header of a stock 4.0 at a junk yard and cut and welded it to match what I had. Not the best, but it works for now.
