KOUmotorsports will be offering stainless O2 housings shortly. Either in internally routed (quieter for street applications but still offering improved flow and reduced boost creep symptoms), or externally dumped housings.

After we conduct in-house fitment and performance tests, they will be available for $100 shipped to your door. We are currently taking orders for the first batch.

Here's a pic of our internally dumped prototype:

i'm in those look awesome. I want mine internal dump.

Me want internaly dumped.

Let me know how the external fits(if you make a prototype)! My current setup has a punishment racing o2 housing with an external dump but the damn thing rubs against my radiator fan making a very annoying front end noise, and dumps right on the frame Very interested

Hell if you produce the internally dumped I just might have to go that route though. Looks nice!

I have to admit, it does look pretty good.

I want a external dumped one, let me know when you have them, if i don't have mine from a friend who said he was building mine, ill buy yours.
