Headers without question. After that, move onto a ported TB, cam, then heads if you want to go that far.

ARH have a great (and only) set of LTs but are quite pricey. Alot of people are trying out the JBA Shorties which is about 1/3rd the price and still produce good numbers.

Yeah, you dont wanna replace the y-pipes if you go w/ long tubes as youd be wasting money. Decide on shorties or LTs then if you go with LTs, worry about a y-pipe.
