Im about to purchase pnped manifolds, crosspipe and upipe from a 04 forester XT to put into my 02 wrx. Are these interchangeable? Ive noticed on the grimmspeed site that 06-07 wrx / fxt is a different item than 02-05 wrx/sti/lgt. I dont see why they wouldnt be interchangable but I also dont see why grimmspeed would have them separate
