Hey guys how can i modify a 00-01 franken car mid pipe to fit the 3.5l 02? anyone done it.... thanks

 

All the other holes in the midpipe need to be sealed off, except the breather hose.

 

look at the pic above and you should see you could just cut the end of the breather line off the 00/01 midpipe. make sure the main breather line will still reach after its cut though and you should be good to go. i would cut as close to it as possible and file the end down.
