reading your mods i think it would be over kill... i think that it is something you MAY want to consider if you are in a forced induction or SERIOUS all motor setup.... if you are looking to eak out some more power id hit the other side of the formula
more air + more fuel + more spark = more power
you have been focusing soley on air.. (from teh mods in your list) so now pick up the slack... maybe MSD kit, or adjustable fuel pressure regulator... are you staying all motor or going with F/I? cause that has a lot to do with the advice id offer...
on a side note. i try to ONLY buy quality stuff... adn as far as cats go random technology is who i would go to...
