Question about the Dynamaxx headers.

I looking into getting these but I just wanted to see if anyone has had experience with these.

Any quality issues? power gains? how do they fit? etc.

Also, I understand that the Kooks are really good. How would these Dynamaxx headers compare?

Thanks.

 

dynomax + search = your answer

 

They look like good quality headers, they are stainless which is a plus and come with cats for a decent price right now.
What I don't like about them is they aren't available with an off road pipe option (though they look just like the FLPs that do have that feature) or without the EGR or AIR fittings if you don't need them, plus I prefer slip fits versus flanges but at least flanges won't come apart once bolted.
Flow wise all long tubes are likely within a certain range, though I do prefer headers with a longer collector like the QTPs or Kooks, not the short ones like the Supermaxxs, FLPs and SLPs have.
