Honestly, I'm not sure how thick it is. I just know that people have mentioned that Kook's flange is thick in comparison to some other brands of headers. Kooks are the only header I have any personal experience with, and it's been many years since I did my install. I just know that I was very happy I heeded the advice to use 1" bolts. Between the flange and the gaskets, there wasn't a lot of thread left over. I used Percy's dead soft aluminum gaskets, and they were quite a bit thicker than the gaskets that came with the headers. Other gaskets may not be as thick as Percy's.

Thanks for this.
I will look and see if Summit offers the same bolt in a 1.00 instead for the 0.750 that most of them seem to be....
If I find it I will post a link!
I highly recommend a set that is made by Spectre that has a hole drilled across the head of each header bolt and comes with wires/springs that you put through them to connect paired bolts on each side of ports. They can't back out. There are others with split locks and stuff, but these seem to be easier to use.
Part # 4668 I think.

Can anyone post a picture of the merge spike?
Total PITA to install though, and by the pics posted the locks might not fit on all the bolts on these OBX headers though. They were extremely close on my Pacesetters.
hey man i just ran my car tonight at firebird raceway in phx! 65 degrees, da was around 1600. i have OBX-R longtubes, custom Y with custom catback, 98mm ftp lid, 273's, steel drive shaft,stock converter, fan switch, with an A4. i ran a 60ft 2.052, 13.289 at 106.75mph, i was expecting quicker but no tune yet and my 273s not helping much of coarse, hope this helps i know im an ls1 but just to give ya in idea. i like the obx, passenger was a bitch but thats it.
I placed an order for these this morning! Looking at the pics.makes me wonder if a kooks y-pipe would fit up to these with some reducers and triming of the y's inlet to put it in the right location?

I bought an eworldsales (ebay) stainless steel y-pipe and I intend to get some 3.5--->3.0 reducers to make it work. Im trying to keep my entire exhaust system SS.

I noticed that the SS y-pipes that are left over from the LPP knock offs (ebay headers) have started selling now. I wonder if people are buying these to modify to the OBX style headers now lol. Im glad I won the y-pipe I did because I would imagine that ebay will be sold out of y-pipes soon

I have a set of these on my car,
They fit perfectly, just 1 small issue, I had to shave off the top of the steering shaft bolt as it was slightly hitting on the 3rd tube.
That is probably my fault since i put a thicker gasket.
