Vibrant Performance Sedan Exhaust (Finally)
#19
I wonder why they chose to go with a single 3" over a dual 2.5" or even 2.25". Plus the additional turbulent air from the merging. Maybe the dyno testing will show the extra back pressure helps on N/A applications.
The overall flow is much less.
Dual 2.25" = ~31.79 sq in
Dual 2.5" = ~39.25 sq in
Single 3" = ~28.26 sq in

I was kinda wondering the other day if you guys with TT/SC setups might realise some substantial gains with a one off setup. Sorry to go off topic

Like I said in the earlier email, the dyno testing will be done on Monday afternoon
Thanks everyone for the comments! Once the dyno testing is done and the new pics are taken, it will all be uploaded asap! Thanks again.

The reason was we wanted to try something a bit different. Most of the other companies have dual 2.5" into a single cannister. We wanted to go with a 3" system to see if we could offer one system to the N/A and the FI guys..

Like I said before, I don't see how this would be a good FI choice due to less flow capability than a dual 2.25 or 2.5 kit? I may be wrong but it seems like between the additional turbulence of merging the two and the lower total area it would not be a good choice for FI.
Time will tell.

While I might agree in part with the size thing, I don't agree with the merging turburlance thing. If merging is really that much of a problem, then wouldn't X and H pipes also pose a "merging" problem? As flow goes past each other there.
Also each manifold is a 3 into 1 merge collector. Even headers do this. If anything the merging would help scavanging, not hurt it.
