Ok I am about to go insane for choosing headers. But I think I found some they are hookers but with no y-pipe. So could a exhaust shop mod my current y-pipe or are these headers so off that I would need to either buy the correct one y-pipe or make a new y-pipe? But are their any headers out their that would basically bolt right up to my stock y-pipe.

 

Dude you probably would notice like no gain with the stock y-pipe. That is the most restrictive piece of the entire exhaust. I got the hedman set with y-pipe and dont really like it. I would recommend you to go with the Hooker set that comes with the y-pipe. The AIR and non AIR versions are both great.
