Bob,
That same "Truckin" article (Oct 97 pg 167) that dynode the
stock 5.2L did one more dyno run after installing Mopar headers &
Borla Performancecat back exhaust. They gained 34 HP at the
rear wheels.
Stock 5.2L 160 HP @4500rpm
5.2L with MP headers & Borla Cat Back 194 HP @ 4500
So your cat back & headers should should put you well over 200 HP easy.
Good Luck
Mike Catlin
