Does anyone have any experience with this thing?

Who actually OEM's it for NOPI?

 

With the difficulty of install I would not get a cheap header, once you put it in you dont want to do it again. Get something that others here have used. I am using Strup headers which are a copy of the DC headers. make sure you also get High flow cats or test pipes. I recently installed my berk HFCs and they really make a great combo with my headers

 

yeah im running topspeed headers and no problems so far (had them on for 2 years)...i would stay away from those nopi headers..not too many people have tried them. stick with something tried and true. and definetly get some hfc's. stay away from kinetix though...
