well i am a weapon dealer and have yet to actually see these. i called to see when they were available and was told not yet... whatever that means. weapon r makes some good stuff just getting it from them and them keeping stuff in stock is horrible. but nothing nice to say about scydyne either though. my buddy ordered a header from him and almost got screwed he finally got it but it was like trying to pull teeth out with a door knob. so i really guess i cant answer that. wish i could. if you can get the weapon r one im sure its a good producty thier stuff usually is pretty good.
