Like the title says, I've got a Silver GFB Stealth FX fully adjustable blow off valve for sale. Its been on my car for a little over a year and is in great shape. It has a few scratches from the install and uninstall but are not noticible when it is installed on the intercooler. This is a direct replacement for the stock by-pass valve on the WRX (Heard it works on the STI but I don't know first hand).
It comes with the standard whistling trumpet (not the long one) and a brand new Subaru OEM gasket (I ordered two when I decided to put the stock one back on).
Looking to get $130 shipped.
Any questions feel free to PM me, I'll try to have pictures available later this evening.

John
