I can't read it. Re-do it.

Re: everyones manifold designs.....
 

just a design idea jd thats all im not claimin it to be the ----

Re: everyones manifold designs.....
 

Notice the runners are paired but they didn't divide the collector. Pfffft.

Re: everyones manifold designs.....
 

its still loud but its toned instead of noisy, its at 97db went to stereo shop to test it.
the thing I like best is that I can here the turbo spools loud as ---- other than exhaust noise.

Re: everyones manifold designs.....
 

isnt that how most non-t4 manifolds are?

Re: everyones manifold designs.....
 

Nope. It's pretty hard to pair 1+4, 2+3 on a Honduh without full topmount action. If you look at a split turbine housing vs conventional 4-1 merge collector grouping it's 1+2, 3+4 which has exhaust event overlap if you tried to divide the collector.

Re: everyones manifold designs.....
 

Unless the turbo is facing forward. ;) Then any symetrical manifold is paired correctly.

Re: everyones manifold designs.....
 

Ach, correct.

Re: everyones manifold designs.....
 

ahh now i see it...

Re: everyones manifold designs.....
 

But don't you want 1+3 and 2+4 together? I might have been mislead at one point in time.
