Tri Y headers..

**BlitZ** · 03-02-2008 10:39 PM

The latest craze...

Are they that good? has anyone got back to back dyno graphs for them compared to something like say JDM 4-1?

Is there any sacrifice in power in any range over the traditional 421 or 41?

Bang for buck headers for a b18c 1.8L.

For 1.6L we havn't test them yet, but i heard toda headers are one of the best headers for a B16a 1.6L

So are 1-4 not merged? Or is it merged 2-3 and 1-4, just like 4-2-1 headers?

**BlitZ** · 04-02-2008 09:44 AM

actually..

Tri Y
its ports 1-3 2-4 at the secondaries

Traditionally... its
1-4, 2-3 at the secondaries

tri Y merge the first 2 early and then merge the last 2 very far down the track.

Supose to reduce turbulance for better flow

Hmm, wouldn't a tuned length 1-4, 2-3 have less turbulence than a 1-3, 2-4 since you won't have pulse collision at the first Y joints? Of course, I agree the tri-Y is better if you were comparing to the cheaper untuned-length 4-2-1 headers.
