What I did on my CR was put the sidepipe on the header flange on the CR it has four bolts I used bottom header hole top sidepipe hole this was just to get an idea where the hole should be once you figure the lenght and some idea how high to go, I used a angle die grinder with a rotery
rasp to do all my cutting works very good and easy to control just remember cut a little you can always make it larger later.
