Is the donut gasket on TRD exhaust directional? When I installed it, I don't recall seeing any directionality, but perhaps I put it in the wrong way? Could that be a cause of the drone? Instructions didn't mention a direction either.

I can confirm. I put that same Vibrant resonator and it eliminated all the drone. Truly amazing. I dare to say it's "silent" when holding RPMs and idle, but is loud when you step on the gas. Exactly what I'm looking for.

made a quick clip of the current exhaust setup - Fujitsubo front-pipe (catless, dual-resonated) x TRD Special Edition exhaust (with Vibrant Ultra Quiet resonator)

That's a very mature sounding car. I guess the Vibrant is doing wonders with his dual resonated front pipe.
I have tried the dual resonated front pipe and I didn't like the smell, couldn't live with it. Now I am on catted and resonated front pipe and it is so much better. I guess you don't have any drone with your current set up. |

There's still a small amount of drone/resonance around 2600-3000 RPM, but less pronounced than before; the Vibrant resonator helped a lot. Smell wise, I haven't noticed anything sitting in-cabin. I've only noticed a smell if I'm outside the car, e.g. putting/getting something from trunk while it's running. |
