Hey TVT,

I am just wondering whether the headers will require me to reprogram
my ECU (I already have a Speed Innovation N/A ECU tune).

Also, being that I have already upgraded my Crossfire to the best of
my abilities (ECU tune, Evosport pulleys, Needswings CAI, Borla cat-back,
gutted cats, Magnecor Wires and Denzo iridium spark plugs... you name it)
I am wondering how well the new headers will "sync" with the other upgrades...

15~20 HP for the NA seems a bit high of an estimate, but it sure does sound good! If some dyno figures can be provided, you can DEFINTELY count me in, as I've never backed away from a great deal before.

Hope you can provide some answers for me ~ thanks in advance!
