Can i still put Headers on?

Ok guys i have bought a flowmaster 80 series installed about 3 months ago. Now i am getting rid of all my a/c and smog pump. Right now i have the stock manifolds on it.
Now what i want to know is once i take all that off can i put headers on my car using the same exsaust system. The system is only 2 1/4 inches.
Please Help!
thanks
kevin

Yes, however, the neck-down to 2 1/4 will be restrictive.

Well, if you are getting rid of the a.i.r tubes and all that, maybe some super cheap flowtechs or something with a y-pipe would work good with your exhaust.

If you go to a 2.5 or 3" Y, yes, modification of some sort will be necessary.
