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?

We just put Kooks on my motor. Very very nice header. 2inch x 3.5inch collector

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.

Huh....3.5" collector....when did this happen. Now I'll have to go that way for my new 441ci......

Kooks are very nice, thats what I have. ARH even has a 4 inch collector.

I only see 2" primary / 3" collector advertised on ARH's web page.

You guys have any problems with clearence around the steering shaft? I was looking into 2" headers but read some fitment problems.

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