Thread: Kook's Headers

  1. #1

    Default Kook's Headers

    Does anyone have any experience with Kook's brand headers? I am looking on Summit Racing and they offer these w/ Y pipe and a cat. Just want to know if it is worth the large difference in price. Or any other info that you may have about them.

    Be suer to have a look at American Racing Headers and Dynatech.... both can be purchased with high flow cats. These are what I am looking at for my trruck... both are pretty much the same but the ARH have larger header pipe option 1 7/8"..

    When it comes to header's I have little to no knowledge about what makes one better than the other. Which one is better foe which RPM range. And so on and so on. With that being said what makes the other ones you listed @timTom64b better than the other's? What was it about the ones you did or will choose that made you pull the trigger on those ones?

    I had kooks headers and my cobra convert until I lowered it and made custom headers for clearance, but they are very good quality

    The way I look a building HP is the quicker you can get the fuel in and exhaust gases out the better.... this then takes into my decision on the headers I would choose. The ARH are 1 7/8" pipes to 3" collector. The Kooks are 1 3/4. I know that does not sound like much... amount to 1/8 but consider that to the total volume of the pipe and it adds up. I also like the low flow cats... I had a similar combination on my monte ss and performance was awesome. Next thing I look at are fit and finish... to me it looks like a little more overall attention to detai... eventualy my truck is going to shows so I want the little better appearencel. Dont get me wrong I do not believe one could go wrong with any off these... I looked at all three and have made my decision and will order the ARH in the next week or so...
