add in the price of intercooler, intercooler pump, intercooler resevoir, tuned chip, K&N filter, oil catch can, all fittings, clamps, and hoses and your looking at a good $1500+. That brings the grand total to about $3000+. Certainly worth the price of the custom fabricated headers, downpipe, intake pipe, etc. Im sure you could get some headers fabricated for cheaper, but this is quality steel too.
