do bbk shorty headers fit with the stock y- pipe? or do i have to buy an aftermarket y-pipe?, any suggestions. thanks

 

They come with their own y-pipe when you buy them. I'm pretty sure they do line up to the stock y-pipe if you were just buying the headers from someone who is not selling the y-pipe.

 

If I were you, I wouldnt spend any money on those headers. I acutally bought them and sent them back hearing that they were crap. I read somwhere that one guy installed them and saw absolutely no gain on the dyno. But there could have been a lot of factors in that also. Just do some research on them before you purchase them.
