That kind of motor that needs that sort of header often has already had a motor plate installed. Say good bye to Motor mounts

I am sure they will fit fine with an aftermarket k member, probably with a stock one, but I can't imagine anyone that would need these that would still have a stock k member on their car. I'm sure the motor mounts won't be in the way.


Thanks Kooks, I will be buying a set of these in the spring.

Looks great George!

Any chance of getting them stepped .... 2" to 2 1/8" ?

I know Steve had asked you about the strait 2" and the stepped, dont know if you have gotten back in touch with him yet.

Did you see the Pump Gas Drag article yet? Has a Kooks plug in Steve's write up.
