Thoughts on unique header design (Myers Competition)

[cornerbalanced]

Currently in the market. Trying to hold out for SS V1s, but I came across a pretty unique set of headers. They were made by R-Crew (small independent race shop in SF Bay Area) in collaboration with Meyers Competition, well known for fabricating incredible headers. These headers were limited to a run of 10 units.

What do you guys think of their design? Another forum member told me they resembled a Manzo style header, and look like a fairly inefficient design. Construction/fitment is verified as perfect. More so curious about how these stand I’m comparison to other headers on the market. I have seen little/no information publicized about these—primarily because of their extremely limited run, and the fact that the vast majority of people who purchased these new still have them.

Pictures attached.

Good header development takes lots of dynoing and trial and error. Repeat dozens of time, tweaking header design between each run.

Small batch, custom headers are only worse.

I wouldn’t call those unique as it’s a typical 6-2 setup. If you have them I’d run them and test them as that’s only way you will know if they are any good.
It’s best to start with a tuned baseline and tune them after swapping if you want to see true gains.
It’s pretty hard to be crappier than the oem catted headers

no point reinventing the wheel with SS so readily available imo...not worth the headache for "rare" talking points at the C&C

if they made superior power there would be proof of it, even if only 1 header existed

Trying to find SS V1s but I have had no luck. I would be getting these for less than euro header prices which is why they'd be appealing, rarity isn't as much of a factor.

that'd be a good price for a set of well built headers, but you'd have to go in with realistic expectations because there's no data on them

are you buying this set off the guy that works for eibach? imo that's even worse because an industry guy is choosing not to run them. at best they're just "going in a different direction" and at worse they know exactly what kinda power this header does/doesn't make

It's a different guy, I've been trying to reach out to Tony (guy who works for Eibach) to see why he sold. Guy I'm buying from decided to go back to stock/return his car from track car to street car.

What are the primary tube sizes...they look HUGE!

I'm not saying these do or don't make good power, but just wanted to point out this logic is flawed. There are lots of owners/builders who do not post their data, especially if they are racers. So just because we don't know doesn't mean they aren't good.

To OP, personally if you have the interest and the price is right, give them a shot and see what happens. Post the data here and we'd all be grateful for the info.

a fair point, although in this instance there are two companies involved in the production of this small batch (could have been 1, 10, or 100+) that stand to gain from advertising any meaningful gains and for whatever reason they've chosen not to do so. i'm not saying they're definitely no good, we just have very little reason to assume that they are

I've got a set of Evosport headers that will be for sale shortly, if I ever receive my SS order...

As a business that has been in involved in small batch production products I can definitely see reasons to make a limited run and then stop, sometimes the juice isn't worth the squeeze for small businesses in which this isn't their primary business model.

Look at Kromer Kraft, they were a very well known and respected header design 15yrs ago and then dropped off the face of the planet (for various reasons) but there are still very little dyno graphs publicly posted with their power gains (which for the time were substantial).
