call up rick and say vinny or richie from aleromod sent you, their kit was 2k when i bought it and it probably still is. great setup for the car and everything is bolt up, you just need to do the fab work for the airlines and such. plan on spending around $300 for brass fittings to plumb the whole thing, and dont go cheap, you will only end up redoing it in the long run.
