My stainless snorkle cost me about $400... It sounds expensive i know, but an aftermarket plastic one can cost that much, so i didn't mind outlaying the cash, plus i think it looks awesome... came up like a mirror!!!
here's the breakup of what it cost...
$300 - Snorkle fabrication from exhaust shop - 2 1/2 inch pipe. They cut the hole in the quarter panel and supplied a hose reducer from 3 to 2 1/2 inches from the air-box
$80 - to polish snorkle at chroming shop
$20 - installation of 2 No. nutserts with bolts, got this done at a toolbox fabrication shop, cos you need a special machine to install nutserts, very similar concept to pop rivets.
$3 - Hose clamp from supercheap
$5 - some pinch mould from clark rubber
it took about 30 mins to install it once i got it home...
