is a intercooler piping kit really worth $180???? thats how much they are going for on ebay. I can just go to auto zone and get the pipes for $50 right?!?!?!?!

$180 is very cheap for a quality i/c piping setup. The piping will make or break your turbo system.

You can purchase the pipes (exhaust pipes) at most any store, but unless you have a mandrel bender, a tig welder, hose couplings, clamps, and a lot of free time, you wont be able to do it yourself.

A friend of mine with a Galant VR4 had an intercooler piping set custom made to the tune of about $400. Just a ballpark figure for ya.
Dont trust the ebay equipment, get a tried and true kit.
