Hey I have a 1980 Corvette and want to upgrade the exhaust and make it loud and simple. I want to install hooker competition headers with 3 bolt flange and right from that I want to connect a 3 bolt cherry bomb glasspack, that is 20' to 30' inches long. So my question is will it all fit??!?!?!?!?!?!?!?!?!?! beause God I hope so.

It should but does your state have emission laws? To do what you want the stock smog will have to come off.

I live in michigan. but i hope itll work, i tryed finding side headers with 3bolt flange but cant find any

I live in Ohio and last year I decided to make my Vette the way I think GM should have in 1980.  Among other things, I removed all the smog crap and installed tight tuck headers, 2 1/2-inch dual exhaust and Magnaflow muffers.  I also installed resonators to tone it down just a little.  It still sounds great but not so loud that it will attract the attention of the police car setting next to me at a stop light.  Plus, unless you open up the hood or look under the car, there is nothing on the ouside to draw unwanted attention.  As far as what smog stuff is exactly required in Ohio is kind of fuzzy.  There are only a few places that even require yearly smog checks and I don't live in one of those.  If a car is over 25 years old, no check is required.  Also, I have "Collector" plates which requires that I have a primary car other than the Vette for my transportation whiich also exempts my car from inspection.
