That "KSpeed" header or whatever it is...Is simply a remake of the OBX Header. Of course this is my opinion but I looked them both over and in fact did purchase the "KSpeed" Header from Ebay about 2 years ago. It bolted up just fine, everything aligned right where it was supposed to and it really let the car breath. I did notice a slight increase in responsiveness, as far as actually HP gains I couldn't tell you. It did seem to gain a tad bit but I am not going to start guess. The ONLY REAL issue I found was the exhaust ram (I believe that is what it is called) hook up on the side of the header was slightly welded on a forward angle and made it impossible for me to hook up the stock exhaust ram. SO I capped it off and simply removed it from the intake of the vehicle. I spoke with a local performance shop and they said this was no real issue as the end that hooks into the intake usually gets carbon build up and fails to work after a certain period of time anyway.
Aside from that this headed(Kspeed header) has done its job and held together. For the price I don't think you can really beat it. Still clean looking and it is apparently real Stainless as well LOL since it hasn't rusted. I would recommend this product to anyone looking to save some money and still get the looks and performance out of it.
