Look at sound tube,,,,..,.,. then look at the SIZE of your throttle body....
NOOO WAIIIT Look at the STOCK intake...
you got rid of it,,, already./,
the RIPPPLES NOOOOO YaMAhA!
What DO you think goes faster?
Stores more energy
REMEMBER
they said
FUEL was important
its jUst
STOCK this motor comes TuNeD
(LIKE) a bike
we know it comes with a HEadRoom TOO!!!
2500rpm I HIT GAS and............................ NA POWAAA
Tha thing makes 151 POUND FeeT!!!
meng
all I can say is

Well op was asking purpose of sound tube. Some say its useless just for sound, I think it has to do with air dynamics inside the way they flow. I dont care what other people think, I truly think it affects it just a tad. Losing hp? IDK about that one.

I cut mine off [plugged] and my mpg dropped too. Temps were between 60-70F for that whole week, after driving car over 200 miles, so my ecu relearned.. Then, month later added the TRD intake and it dropped 1-2mpg. That, I can explain with the air to fuel mix ratio and temp.

People will say no, it has zero purpose and no air goes through, but yes it does. After the elbow if you turn car on and rev, you can feel the air pushing through. Then if you put your hand at the end where it connects to firewall, you can also feel it there. I've tested it.

Now concerning the main purpose of the sound tube to affect air dynamics, it is not super important for that, perhaps even insignificant, but yes it still does affect the air inside imo. The greater importance engys put it there is for sound generating.

In other words I'd say 95% sound, 3% air flow and 2{?} for mpg.

Did you not read the thread? It very clearly eliminated the tube as the impact on MPG.
It is a noise maker only. I can take a piece of pipe hold it in an open room right now and feel air move through it. Hell the way noise works is by pushing air so of course you feel it. It what way would the air it moved be of any benefit anyway?

I think he's saying it's working similar to a resonator. I think it's more likely the car was quieter so the driver subconsciously is accelerating more to get the same sound before shifting, therefore reducing mpg. But hey that's just my inference
