So, on firday I just installed the OBX header and for the most part I think I like it. But I got 2 problems w/ the whole thing. One being it does sound a lil bit to ricy for my taste but I guess thats what I get w/ taking out my cat. And two is I can't keep my foot off the gas, now that I have the header in for some reason it seems my foot got heavier and my fule tank got smaller....IDK. But like I said for the most part I like it, I also got a tune form Tom and hopefuly it will kill my CEL as well. If your looking in to getting a header than I would recomend it, the Z-tec guy's love it and I have no complaints my self. It's affordable ant the quallity is there as well.
