Default 2" primary headers
Looking to go 2" with my N20 418ci motor. I know I am leaving power on the table right now with my Edelbrock 1 3/4 stepped to 1 7/8 headers that I had on my 347ci motor. The question is who's 2" to go with. Stainless works or Kooks.

Are there other options?
If not, of the two mentioned, who has the better all around design?

Kooks headers for sure. Quality is second to none.

Didn't realize Kooks was a 3.5" collector. That alone makes the decision a lot easier.

If you actually call and talk to ARH, they will do whatever size collector your want.
