It seems louderst under 25 mph at 2000 rpms.
Typically what happens to the sound over time? How long does this process take?
I bought a used TRD from someone who'd driven from TX to Yellowstone and back, so it should have been quite well broken it.
My experience/opinion was:
- idle-1500 - louder, but sounded ricey to me
- 1500-2500 - cab drone
- 2500+ - nice performance v6 exhaust note
I removed it after a couple of weeks as I spend 95% of my time below 2500 rpm and the ricey to droney sound was too much for me.
Exhaust sound is very subjective, everyone hears things differently and either you like it, or you don't. I wouldn't expect the sound to change much, you might adapt to the sound though.
