What is a Japanese manifold? Topic is solved

[j-dawg]

Haha and I thought the VS posters were harsh!

To be fair, swapping exhaust manifolds and testing both setups is a pretty tall order when everyone acknowledges the differences are likely small at best. But hey, maybe it's not always important to be fair.

True, true. But that's the point - if these things make any difference, it's so negligible that you'll probably lose more performance by inducing exhaust leaks through your terrible work than you'll gain.

The Japanifold's resistance to cracking does seem like a tangible benefit to the part.

Oh, and "small engines need backpressure" - if I hear that one more time I will cancel my internet service and live out my days as a pre-Instagram hermit.

That's not gonna work, there is too much to learn from you. For our sake, keep posting!

This is definitely true when I decide to do this. I'll get an exhaust leak, think that's how the new manifold's supposed to sound, and subsequently convince myself it's awesome, and that the poor car's WAY quicker.

One question remains in my mind: are Japanese and R manifolds mutually exclusive like the photo suggests?

Or

Some of the text I've read hints that a manifold can be both. For what it's worth, my "R" manifold was sold to me as such, but is stamped "Japan".

[erikv11]

R manifolds are all (also) made in Japan.

The name "Japanifold" was applied to the early style ones with the separate runners, to tell them apart from the original 850 manifold. Then along came the R manifold, also made in Japan and stamped as such. But R manifolds look different so it's easy to tell them from the others.

The picture in the other thread posted by tryingbe 4 posts down are working fine.

You can also search google images for "japanifold" - lots of pictures there.

Yes
