I for one am a HUGE fan of craig as well... i was one of several guys who recommended jimmy to go to craig to get the piping done for his turbo setup.... craig has also made a cat-back system for my car as well..... however, when it comes to headers, the 2zz is a really fussy engine, and its not just a matter of chucking on a header with a bigger set of runners and a bigger primary... almost all the big name aftermarket headers out there (TRD, C-one, Trial) have had hours of R&D invested into them and still end up loosing power somewhere in the powerband... so far, out of all the aftermarket headers out there besides the PPE, power is made either in the low-end and mid-range but top end is lost... or power is lost throughout the whole rev range except for a few HP gain in the top end.... so id rather pay an extra coupe of hundred and be 100% certain about what sort of power gain i will b getting and where in the powerband the power will b made.... there is always a risk/uncertainty when u go custom, well... at least for the 2zzge......
