The vortech can be had for $3,050 and a set of msds headers are only around $600.00 and as far as the cat back goes make your own:) for under $400.00 and buy a Compucar nitros in a bag kit for $400.00!!! However I woundln't recomend any thing over a 35-40 hp shot when used in conjunction with the vortech!!!!
The turbo is a nice option too!!!!
