I've got both, I've got an APOC Cai and a custom exhaust. In all my logging i've only gotten 1 degree of knock retard and it was just for a second. Thats it

knock before and after header install. About 1.5-2 deg average less after headers.

mn2k - Thanks for the info...

Anyone with an '01 and a DHP ?

Seth - is your timing advance crazy-off or something? Its def. a weird situation. Maybe you have a faulty knock sensor or something??? :confused: Let's hope its not something fudged in the valvetrain etc.
