Thanks! On stage one until the powertrain warranty is close to or done. Have the ram air, and pulsar at the moment. And dont want to tag the pcm as automatic warranty void here. That's why the kooks is really appealing. ARH and SW are beauties also, sound amazing and work well(following Cammed Ram, Hot D@mn Ram and Frostbite Ram on utube), but require tunes unlocking pcm(as far as I gather). Pricey, but I think that's the extra catalyst material in the green cats. 400 count instead of 200 count. Headers themselves or with off road pipe aren't that much different from other quality headers. I really enjoyed this thread about a mod I am looking into, thanks!
