The exhaust is a good point, i BELIEVE my current exhaust follows the factory routing but i can't be certain until i check. I didn't have to deal with that before as i had dumps.
What exhaust do you have? If you post a side picture of where it goes over the axle i could probably tell you if it will work. I just went through this.
Flowmaster tailpipes do fit with a panhard bar. Other than that I think it has to be factory exhaust or custom made. I can say Bassani and Magnaflow definitely don't work.
For a drilling just get a center punch, a 1/8" pilot bit and a uni-bit (stepped bit) that goes up to the diameter of the large holes. Home depot has all that stuff. Get good bits or you'll wish you did. Drill slow. It ain't that bad.
