alright so here are the bolt ons i have for my ride...skunk2 intake manifold aem intake dc header cat back exhaust and a apexi vafc which i will be getting tuned once everything is on my main question is what can i do about my cat without messing with the computer i have obd2 so i wondering what to do i wanna run a high flow cat but im not sure is this a good setup so for let me know i need your info please!?

 

Might want to ditch that skunk 2 intake manifold. you really need more modifications to the head to actually see gains from that manifold. just buy a euro r intake mani from hmotorsonline.com they cost 225. there is some modification needed however there is a big write up on it either on here or on hondaswap.com. that vafc sucks. they are ok but i was not happy with mine. i did get 10hp out of it but i sold it and got hondata...its purely up to you and how much you want to spend. there are high flow cats that have an o2 bung welded right in to the cat for obdII cars. so there is that problem. other wise not a bad set up. get a merge collector made for that header. you will like that a lot better
