I called Joe and he said the sidepipes are 3" inside diameter. Is this true? I'm probably ordering the sidepipes this week. I have so many other things to purchace right now i figure i can always go back and modify them at a later date. I cant wait to see the body buffed out.

A&C's side pipes work quite well...Joe has a 500hp 427 in this cobra and I used them with a 457 hp 428. I damaged one and replaced both muffles with Classic Chambered Mufflers....like the sound better, easy to install
that being said you can't go wrong with the pipes from A&C

They measure 3.875 inches on the ID. I had to modify the new baffles to fit. The old baffle was very small, too much restriction for me. I want all the HP I can get.

Car is back together, took it for a little drive Friday evening. Holly crap I thought it was nasty before. I have a ton more HP than last year. You bump the throttle too much it starts spinning the tires. Has anyone had trouble with wheel hop? It's not terrible but it's there. I was told the rubber rod ends on the 4 link can cause that. So I'm replacing them soon, just wondered if anyone else has had this problem.Thanks,
Dave
