Kook Size Headers. HELP?? Hey Guys. I need to change my exhaust Headers. Going with KooKs and bye bye to the cats. What would be the best size with my Modes. 1 3/4 or 1 3/4 stepped to 1 7/8. Or just go to 1 7/8? With this big Cam. Need HELP.

With the big cam and heads thats what I'd do. I wish I would have known I was supercharging my car when I bought my 1 3/4

They are usually a hair cheaper than stepped.
the 3/4 to 7/8 will just keep a little more lowend tq around, not much, but with your setup, I highly doubt you'll miss a few foot pounds in the lower rpm ranges... if you are ever there anyways
