Indeed stock everything after the header is "droneless".
I went with a resonated/catted (cat is from an STI,supposed to high flow) Front pipe and JDM quad exhaust.
Note that i wrapped the front pipe as i didn't like the heat radiating from it into the cabin during the summer days.
And changed all hangers (5 of them).
It was all done in increments.LOL.
First was header (EL and wrapped) then front pipe followed by wrapping FP then quad exhaust and finally hangers.
In this way i was able to experience the changes and was genuinely surprised by the effect of the hangers.
There was some drone after i added the TRD quad exhaust, around the 2-2.5k rpm when cruising and then I fitted the hangers.
And the drone disappeared, almost.
The reverberations from the exhaust into the cabin also disappeared. (read as less boomy)
And no it was not a psychological change.
