will pacesetter shorty headers for a 2002 5.3 bolt up to a 98 Z28?

 

AND clear everything....

 

I'm sure they would bolt up to the flange but as far as clearing everything and bolting up to the rest of the exhaust, I dont know, and i honestly doubt it. If the clear and dont hit everything on the way back, you'll still have to probably get some kind of exhaust fabbed up to mate to whatever Y pipe he's running. Not worth the hassle IMO. Longtubes are cheap...
