ats manifold sizes

[dzlpwr]

Does anyone happen to know if the exhaust exit openings on the ATS t4 "Bigfoot" manifold are actually any larger than the standard t3 manifold? I have never seen the two side by side to compare. Just trying to find out if it is worth buying over an adaptor plate.

Well up until a couple weeks ago I had only seen actual T-4 footed center sections, drilled tapped and ported to run a real T-4. Then I looked at one a buddy had, brand new, and its un-drilled with T-3 port openings.

Do you know if the exhaust openings are actually any larger on the t4 flanged center section as compared to the t3 one? In the pictures that Ive seen its hard to tell.

Ive seen them both ways but the most recent new was was T-3 sized. I dont know if this manifold is a mistake or a running change they made.

There is a picture of the old center Ive always seen. For some reason ATS's site isnt working.

There is a better comparison, The T-3 opening is more oval and the T-4 (H2E) openings are rectangular with radius corners.
