Just changing from my '09 non-cat header (it's for sale) to Fullsack X header made a very noticeable differerence to me. More usable 6th gear and way less heat. Not sure going to true duals over stock would show much gain?

i just went to that site and the powerflex header sounds like a pretty good option. i may try them. 230 is half of a tru dual header. of course then i also need to do a stage 1. right now i just run slipons and everything else stock
