Ok so I work a job where my pay wildly swings. So I just got my 06 and I plan on adding a full header and, airbox and remapping or flashing the system as soon as I can, whether it be next month or a few months down the road. Whatever needs done. Keep in mind I am not a mechanic and all of this is new to me. I will be using a shop or myself and dad will be taking on this. Pretty much immediately I want to add slip ons. With what little I know I think I've narrowed down my choices. Two Brothers, Vance and Hines CS-ONE OR MAYBE HMF. Are these good choices that will work with a header down the road? What do you guys think? if so will I see a performance gain once. I do the additonal work with the air box, header etc?
