Any before and after gains with Kooks headers?? I see alot of people promoting the Kooks headers, but I haven't seen anyone post any dyno numbers. Anyone have any before and after dyno numbers?

Re: Any before and after gains with Kooks headers?? There was a post maybe a week ago with some dyno numbers. The numbers compared his before with SLP to after with stepped Kooks. He also switched his gears at the same time so he figured his dyno was 5 to 12 hp low. All said, I belive he picked up 12 rwhp and if you add the lost hp. from the gears, it ends up being between 17 and 24 hp. more then the SLPs.
