Drivetrain Exhaust Port Matching
Just so you know no agenda w/ or against Jan. Yes, a little scrutiny of the craftsmanship on my part but nothing more. If anything perhaps the positive is that Jan will review RMW "standards" w/ his header manufacturer. I can appreciate that Jan does not inspect every piece made. Anything else I have seen pics of has been flawless.
Bart,
no problem, I never took it as such
I do inspect all of the headers if I am in town before they go out. I am more worried about proper welds as we weld them on the inside versus those that weld on the outside. (outside welds are more prone to crack)
I don't want to grind away at the welds for beauty's sake as the ports are larger than the exhaust so there is no need to do this. It's just cosmetic
Believe me, we care about the quality of our products and that's why they are made here in the US with US stainless steel
pics as promised (first is with the new metal layered gasket I had made up):
the old copper style showing that the header is much bigger than the ports on the head (ignore the leaks...Jan now supplies a better sealing gasket):

Here is a better pic of my street header flange, since you made comment about the original pic. Again, cosmetic only, and only until installed.

I was planning to wrap mine but was told it's not needed. A ceramic coating can't hurt since the cat is in the midpipe on the RMW setup.
Another thing about the Milltek....the ports are stock sized. comparing it to the outlet on the RMW head....MAJOR roadblock. Like trying to hook up a 2" cat back on a 3" primary

not needed but some have done it
I just cleaned up PGT's header when he sent it back after I changed the choke point since he now has the head/cam combo

I'm not sure its permitted to have a civilized exchange here
. I think at this point you were supposed to make a reference about my mother and I was to counter about meeting up w/ you in a dark alley. On a serious note, I appreciate the response, thank you.

Interesting looking manifold. does the tigher bends after the flange effect performance?
The Janspeed is wider, but I had to modify the heat shield to allow it to fit over the manifold due to its wider design. Have you played with using the wider area if the heatshield isnt there?
Using this pic as its the same as the Janspeed which has shown good gains over here in the UK.

EDIT: BTW can we get a pic of this gasket mated up to a milltek header or a stock head for all the haters to grind their teeth to?!?!?!?!?

This is a true equal length header unlike the janspeed
There are a few innovations inside the header that you can't see that are unique to our header
I should have taken that pic as I had the RMW, the Milltek and stock all side by side, but will gladly overlay the gasket over the stock header when I return home and post the pic for you. It's downright scary how small the ports are on the stock header (and head).
