TTI Exhaust install 1964 v-8 Barracuda

The tail pipe hangers were first tried at the hole on frame, after mounting the muffler hangers I could tell that the tailpipe hangers needed to be moved rearward. The instructions HINT that you could use a existing hole, but that it might not be in the right place. Drilled a new hole about 1.25 inchs rearward. VERY tight location to drill, had to cut some drill bits shorter to fit my angle drill. There is also a metal seam inside the frame close to that location that you can feel with your finger only which you must work around also.
Then when the tailpipes are loosely installed you can test fit the mufflers and the x-pipe. The spacing between the mufflers can be adjusted to fitt the pipe in the proper location.
