I got the headers last night, but there is no y-pipe with them! WTF! I don't see any disclaimer that the headers don't include a y-pipe, I'm hoping it is a mistake. I emailed them right away, and I will call them on the phone really soon here.
I am hoping for the 10/15 improvement, but who knows since I am also going to be putting the 70mm T-Body on before it really hits the turf.
BTW, the headers I got look very clean inside, no overhangs or anything. Do you think that I should still widen them out a bit?
