I thought it was interesting to see the differences, so I figured I'd post the pics.

Didn't even know they kooks made 2 inch. But definitely a good time to get a heat coating on them.

I've got a few other updates going on w/ the car, so I don't know if I'll have an exact 1.875 vs. 2" comparison, but I'll see what I can do

I just thought it was interesting to see how much different the primary length was as well as how tightly they grouped the pipes together

I'll test fit tonight and may send out for coating... not sure if it's worth it or not. I'll have to see what's available locally, but is there a particular type that people really notice a difference with?

ARH 2"


LG 1.875"

Do you happen to have measurements of the primary length? I can measure mine tonight.

It seems like OBX has the longest primaries and the others seem fairly comparable?

Unreal

I can measure. I know the ARH have ~4" longer than the Kooks 2". You can see the straight section of pipe before the collector where the kooks has the collector right off the last bends.

Purely for comparison as primary lengths came up in the conversation check-out these Stainless Works headers. Top one is my old 1 3/4" SW setup and I'm currently upgrading to the 1 7/8" SW setup. The primary length is INSANELY different. Same brand but newer design. I'm impressed and cant wait to see what they do.

Unreal

Measured 27" on the ARH.

31" primaries on the SW 1 7/8's I just installed. They say the primary length really helps with the tq.

I'll find out soon enough.

When did you order those kooks? They appear to be the older style.

Do the flanges on anybodys headers look like this?

Maybe a month ago, took forever to build one of the parts I guess. What do the newest look like?
