$350 shipped and insured in the lower 48. If you live somewhere else we can work something out. It's for an 04 WRX and won't work with other years. 1 scratch in the plastic, works perfect and is unmarried. Comes with the controller, cable, plug in for under the dash, manual, CD, computer cable, power supply, and I think I still have the originial box. Pics available on request but I'll have to borrow a camera from a friend because mine didn't pass my durability test.
Stromung catted downpipe (don't look online, you won't find it anywhere). I bought this as part of a complete turbo back system 2 years ago from someone that is/was a dealer for Stromung. This was a piece that never made it into production. It's non-bellmouth, 3" stainless steel piping and has 3" outlet (kind of egg shaped, not exactly round, a stromung thing). It is a metal substrate converter and also has an O2 bung where it bolts to the turbo for a wideband oxygen sensor. It's a short downpipe, same in lenght as the divorced wastegate one they sell now. It was used for about 24,000 miles and is in great shape. Starting off at $175 shipped in the lower 48 for it.
Lastly I have a brand new rubber seal that attaches to the air splitter and seals up against the intercooler for an 04-05 STI. It's still in the package and cost $32 new. If you're changing intercoolers and hoodscoops you'll need one of these. $20 shipped in the lower 48.
I will also have a 3" divorced wastegate catless downpipe forsale shortly. It's a long one, not short like the Stromung. I forget what brand it is but it's stainless steel and once I get my exhaust the way I want it I'll ask $150 for it.
If you're interested in anything send me a PM or reply here and thanks for looking. Oh and I'll try to get some pictures if anyone wants them, but my camera is dead so it might take a day or two.
