Well guys I'm excited, my new Kooks 6753 headers finally showed up. 1 7/8" primaries with their trademark 3" spiked merge collectors. The OBX's are already off the truck and sold. Now I have to find time in the next few nights to get the headers installed and then get my new true dual 3" setup installed. Here's some pics as a few minutes ago when I unboxed them to check everything out. Nice equal length primaries, clean welds, etc. I don't see where the ARH headers have anything on these guys and they almost look identical in design. Maybe the Kooks even flow a little smoother (straighter). I'll let you guys be the judge. Here's the pics you've all been waiting for. Side note: that's not welding spatter you see inside the collector, it's just metal shavings and a little bit of oil mixed together. I plan on cleaning teh crud out before install.

Any updates with your Kooks header? has it made any difference? Just interested to know because I might also get this same headers.

I just stuffed a forged 5.7 in and tried a set of F body Dynamaxx headers. = NO FIT !

Just ordered the Kooks. Part # is 6752 along with a non catted Y. I'll prolly chop the Y and go true duals as I have 2 3" Magnaflows in the attic.

Ok I read this whole thread twice.

Simple question. Without stirring up the pot. Why did you try the Kook's rather than use the ARH? I ask simply because I run the AR 1 7/8" and I have had them for almost 2 years now actually just took them off to have them coated recently so they are sitting in my living room. Is it a cost issue or just preference?

preference. the kooks and ARH headers are probably just about identical in quality and performance. i think the kooks are a bit easier on the wallet though.
