Just installed new exhaust. Do I need a tune?

I have a 1997 WS6 LT1 which I just put a new exhaust on. It consists of PaceSetter Mids, Random Technology High-Flow Dual-Catted Y-Pipe, and SLP LM1 Catback. I also installed the LT4KM along with it. Do I need a PCM tune or not?

Most of the tuners that I have talked to will say "yes" after header installs.
