Any back to back testing on Eldebrock to other 1 7/8" headers
Eldebrocks are 1 3/4" stepped to a 1 7/8" to a 3 1/2" race merge collector.
No complaints with the current Eldebrocks, other then I stood the car up and smashed a few pipes a bit, and they have been on the car 4-5 years.
It looks like almost a grand for Kooks or ARH, compared to about 650 for the Eldebrocks, then paying someone to tig the collectors on, so still about a $300 difference.

I went from Jet-Hot 1-3/4" to Kooks 1-3/4" and the fitment and finish looks so much better that I think it was worth it. $500 compared to $750

No, I dodn't misss that, but the last time I checked, they weren't putting 402-408's in the newer vettes. All I see in there are results on a smaller cube motor. Other than one guy that says he lost track times while running NA, which is interesting, but I'm not NA.
I'm not against spending the extra $300, but want that decision to be based on reality, not speculation. So far I'm not finding anything that show a justification. These headers have been out for years, you would have thought there would have been a real world header shootout by now. Maybe there has, but not worth posting, as it might not in the best interest of certain manufacturers... I dont know
