I have but I think I had to make a small indent on one of the runners to clear frame nothing big though.. and did notice a mild gain in power on acceleration but absolutely no big HP gain

What did you do with the rest of the exhaust? Did you keep the cat?

Judging by the pictures of them, there's no way those will work with either the computer or the catalytic converter, and therefore the CARB EO they have on those is totally bogus. Am I missing something? You won't be able to keep anything "original" under the hood with the headers they show in the pictures.
