If i can have headers and not be too loud i might plan to do so...the only issue that would arise is i will definitely tune for them. Might not be a good idea, there is no hiding headers, though i could switch ECM modules out or flip back to the regular software.
Might start looking into it. Kooks are expensive, ARH, are 100-200$ more than a CAI.
What gains do you think you can get with Tune + Headers + CAI + Exhaust? I know what i would like to see. Just don't know if that's realistic. I'd like to see about 30bhp increase. That would damn near put the 5.3L at 400hp at the crank, probably 300hp at the wheel. Talk about power hehe, then would just need to re-gear to 3.73.
My problem is i was never into trucks until i got this one. Had i been at the time i would've gotten it setup a little different.
