A few years ago I had the exhause on my 65 hard top
redone from the motor back, stock mufflers 2" pipes no
resonators. She sounded pretty good had a little more
pep and promply burned the transmission gasket on one
corner causing a very bad leak. Had the pipe moved and
then it cooked my starter. There just wasn't enough
room. Took it back factory specs and no more trouble.
Just my 2 cents
