Well... I got the HP Racing header in and installed about 2 weeks ago or so, and I must say that so far I am not disapointed with my purchase. Considering its a temp solution until I get my turbo manifold, Im pleased with the power gains (and they are sugnificant). I can burn through second, and "catch" it without trying. Which is imprssive to me. Maybe not a A+ product..but well deserving of a low to mid B.
The one draw back being the escape of heat with a noticable change in color to the header itself.
