looks like another company stepped up and came thru. i was just scrolling thru sum aftermarket sites and i saw @ andysautosport that they had added the rpm header, then i saw the doug throley header. now i was like wtf?!? but just to verify i looked at the pdf catalogue from doug thorley and surely enough there was an XD application. the base price is $228.00. idk how much with shipping but this is great another good performance mod to add to my wish list. all we need is a good intake mani, and maybe a larger throttle body. and we will have n even better n/a monster
