well as for intakes The Offey will be a better daily driver for you. Reason better low to mid range power & tork. As to the clifford is more mid to top end power & tork. now as for headers once u add a muffler and a full set of pipes The header will all seem pretty much the same. Now if your Building a all out Race car then thats a different story. same goes for the diameter and the power/tork and Rpmband your after. But as a daily driver you realy need not worry to much about Pipe size. hope this helps }[oooooo]
