just don't forget....you'd probably have to pay for another tune after......but that is up to you.......
the cheappest way is to put every part on the car and then tune it

from what i see you need these parts to get the most out of your S/C set up(second hand prices):

-Header(shoty or long tube,OBX will do) ~$150
-2.5" flex pipe (Truebandz) ~$100
-2.5" catback (Borla) ~$250
-2.5" high flow cat (Magnaflow) ~80
-passanger and drivers engine mounts ~$150
-adjustable camshaft gears ~$120
-maybe some cams like Ford Racing st.2 ~$200
-early ported intake manifold ~$80
-65mm throttle body (Focus Central) ~150
-Xcal2 ~$280

so like somewhere around $1000 to get your monster beefed up lol
but thats all up to you.....i got all that from the top of my head

the key thing to do is buying everything used to keep it on the budget :)
