for your exhaust i would go ahead and buy the off road Y if your gonna use the pacesetters.... its alot easier than trying to modify the y pipe you have right now and plus i dont think it would flow as well..... if you see them side by side youll see a major difference in diameter....

as for a trans, you might wanna talk to Jerry... He is danny's (sprayed99) dad and can do the exact same thing as an FLT and do it at a lower price and provide a good warrenty.... my 2 pennies there

and as for a boost friendly cam i would check out TexasSpeed.com they have full cam packages that are a one stop shop...... didnt he have a cam in that engine to begin with??
