The exhaust testing results were published in the Nov-Dec 2020 issue of The Y-Block Magazine. There were some additional tests in that article that were not published in this particular thread. Because this thread was quite old, the pictures of the various exhausts did not transfer when the website changed servers. The article as it was published in the YBM has been made available on the Eaton Balancing website. Those missing pictures are now in the Eaton Balancing article. Here’s the link.

It would be interesting to hear what you think of the quality and fit when you get them.

Thanks Ted. The FPA type are the ones I was thinking of.
I think I'll go for the Saunders shorty that I saw on Ebay for $250.
Due to I will be using the car as a daily driver and from what you were saying about coated heaaders, stainless is a much better choice, and its only 10HP.
I'll spend the extra on the intake.

Ted, Have you or will you be testing Mummerts T-Bird headers? Do you have any expectations of what results may occur? ChrisWhile I haven’t specifically tested a set of headers that came directly from John, there’s a chance they have been already tested depending upon who his supplier is. Here’s a couple of links showing pictures of some of the various headers and exhausts that have been tested thus far which can be used to compare some of the various designs against each other.

I'll admit I chose the aftermarket ram horns for my truck after seeing how they stacked up to the other configurations. While I don't have the induction or head mods, they will be a good choice for a street truck being built to haul a 2500 lb trailer on a regular basis. I looks I'll be making up an exhaust using mostly Hearthrob bits.
And yes I agree that this is valuable info. Heck this whole site has steered this novice in the right direction

Ted, you mentioned, in the test, Fenton cast iron manifolds. What is the deal on those? I assume they are rare as hen's teeth.. The Fenton manifolds have not been available for a good number of years now. There was a move recently to have them cast overseas but still waiting to hear more about that. For now, the manifolds seem to be relegated to ‘collector’ status as those people that have them, seem to have more than one set.

I am sort of surprised that as good '57 stock manifolds are they haven't been reproduced into steel headers. Seems like someone with a tubing bender, electric hack saw & great welding ability would have done this. With the cost of swap meet & ebay manifolds being what they are I'd think they'd sell like hotcakes if they were in the $200-$250 range.Reds makes two different sets of headers for the ’54-’56 cars. The one tube variety is listed at $220 while the two tube variety is listed at $295. Here’s the link to a chart comparing some of the various exhaust manifolds and tubing headers. The headers that are simply a bolt-in replacement for the cast iron dual exhaust manifolds do not typically give much if any power boost over the cast iron exhaust manifolds. http://forums.y-blocksforever.com/FindPost58704.aspx
