well i'm not sure if it is good power ?
as i've not many 3v 5.4's to compare to with only the mod's i've got

dont get me wrong... i'm happy where i'm at, but i'll be looking for more out of it before i'm done

only the header's are di filippo, but as you'd know.....
stock system's are'nt ment to be loud, and that's ten fold for an LTD being a limo

i did'nt relise how quiet it was until "kev gave it a rev" after doing the plug change,
a hoover vac cleaner has nothing on my old system

it's still quiet at idle & low throttle, but opens up a bit when my foots down.
i was thinking of taking one of the muffler's out, but the quiet/loud open throttle suits the car i think
