I am getting ready to buy SLP headers and the ones w/o A.I.R. are cheaper.I think they have to do with emissions but since I already have my cat cut off it won't be a problem.So if you could tell me what they are and what they do I would greatly appreciate it.

AIR = Air Injection Reaction = smog pump and associated hardware. If you don't have a cat, then gut the AIR system as well and buy the SLP headers without provisions for it. Just my $0.02.
