Hello. on my 99 Trans Am so far i have.... Adjustable cat back borla exhaust, suncoast ram air with ws6 hood, underdrive pullys, MAF, K&N filter, hotchkis strut towers tied, frame tied, and hypertech power programmer not installed. I was thinking maybe some pacesetter LTs with y-pipe, or LS6 intake (whats the diff between ls6 and lsx intake anyway? I am doing a stall but not for a while. Let me know what you think would be the next best bolt on for me. thanks

The biggest upgrade, and its a must for auto cars is a stall, you got to get that first. Then Pacesetters is a good choice, very nice headers for the money. Dont get the pacesetters y pipe though, get one of TSP's y pipes. LS6 intake is the best intake to get for a bolt on car. If you are planning on making big power though in the future, get the fast setup.

Whatever u do sell your HPP3 immediately! they are pretty much useless, and whenever u get your headers and intake, u will probably want a tune, in which they will delete all the programming by the HPP3. So just do what i did and sell it on ebay for about 250.

If u do that, u r 2/3 of the way to your headers.

Your on track, you know what you need, start with the stall, headers and intake that should keep you busy for awile.. Deffinaltley dump the HPP3 and get a real tune, you will need it after the abvove mods regarldless. Then start looking at a cam that works well with your stall and other mods. Then of course heads..
