Kooks 2” stepped headers
Hi all....does kooks make 2” stepped headers for our cars? I tried to research a little online but couldn’t find anything. I did find 1 7/8” to 2”.
Is that what these are?

Interesting...I always thought these were measured by the ID. Unfortunately I don’t have calipers to measure the OD.
Maybe these are 1 7/8” stepped to 2” because I can’t find 2” stepped kooks headers anywhere online.
The reason I ask what these are is because I want to get rid of them but want to give the buyer the correct info.

I believe the 7/8"-2" Kooks stepped headers are made for Zip Corvettes.

I had a set of 1-7/8 to 2” stepped kooks. They absolutely do exist if you call kooks you can order them. Now with that said they fit like crap and was the last set of kooks I’ll buy

It was mid range torque. The upper HP number was within the error of the dyno. These actually came into existence for us on two things that happened around the same time. One we were working on a head and cam package where everything was designed around the cam we were using and Leighton Reese's World Challenge race car. We will probably not make them again, for anything else, it was just the right timing.
