Just for the record, I did modify my Super Comps with all the stuff I mentioned:

 

good lookin headers james

 

The ASM's have O2 bungs in the collectors and a provision for EGR, if anyone cares....

 

 

thanks fellas, i still have no idea what i am going to do, probably just get some good long tubes, and modify the y-pipe, hopefully the headers don't go all the way to the first 02 bung, if they do, i'm screwed then, cause i am not going to modify my brand new headers like james did.
