gotta get the already backed up air (from the stock pipes) out before you can put new air in..

#1- catback
#2- Headers and Y pipe or true duels or whatever
#3- intake manifold

went the complete opposite...get the intake and not worry about the headers for a while...i am assuming you already deleted the rear O2s already with having gutted cats or at least have sims...so that saves you one step...intake is better bang for your buck in my opinion...300 vs. 375 plus price of y pipe going to put down around the same numbers...either way works though...no right or wrong here

get the headers out of your way first. larger gain than intake...but way more of a pain. since your cats are gutted just get an ory to compliment the headers. that borla is gonna be lound though.

if you dont have them deleted out of the computer or you dont have O2 sims in the computer still thinks you have cats...your gas mileage and performance are going to suffer probably even worse than before when you had cats...the computer is not getting an accurate reading...
