The only problem I came across, which really wasn't to much of a problem. Was where the pipes came under the tranny mount. I used the universal tube type crossmember, the type you cut to fit and mounts lay on the top of the lower frame rail. I used 2 1/4" pipe and it was very close to touching the bottom of the cross member. I ended up with almost 1" clearance. The rest of the pipes and muffler had pleaty of room until where I had it come over the rear axle, it is a 12 bolt rear end not the original rear end. I mounted a universal 16 gallon tank beyween the frame rails at the back and the pipes have about 1 3/4" clearance from the tank front lower corner. I tried dumping my exhaust ends down in front of the rear axle. That was a bad idea, cleaned the garage floor real good though.
