Was it too much science for you?
For not wanting someone's opinion, you sure offer your own a lot while offering little to no value.

I was trying to be civil and offer a potential alternative backed by proven science - determine the resonance frequency and create a Helmholtz resonator at an interference wavelength. Sorry that you can only troll others when they ask for help, but can't accept an opinion that doesn't align with your preconceived notions.

Also, I believe the word you were looking for was "read" not "real". Congratulations, words are hard.

Typically drone isn't caused by the muffler itself, but the sound wave function leading to the muffler - which is why it's heard closer to your seat than the rear of the vehicle. The Helmholtz resonator when placed just passed the Y-pipe is a 1/4 or 1/2 wavelength oscillator, effectively offsetting and canceling the primary sound wave.
The TRD muffler already has a Helmholtz resonator integrated into it. It's a dual-pipe muffler that they're repurposed into a single pipe with a capped off chamber.





Who had the idea for adding another muffler to the muffler? Lol, I can tell why that guy doesn't like reading.

Good insight. I noticed the secondary pipe and didnít think about it functioning as a Helmholtz. Makes me wonder how the internals look because they seemed to miss the 1/2 wavelength. I guess itís more like a 350z design than a J-pipe I was thinking about.

If anyone in Toronto area wants to buy TRD Pro exhaust, PM me, going to take the one off the rig soon, the drone is not my thing.

Also, when it comes to the whole online thing, pointing out a blatantly obvious typo is a really sad sign of your desperation.

Itís cool though, I wish you and your 4Runner, ole clunky, the best as you install raptor lights and try to impress folks at the next overland meet.

Not cool.

Hey, how much are you looking to get for the exhaust?

Swapped mine with a normal 4R exhaust from a '19 TRD Pro and couldn't be happier. The cruise control still hunts for a gear all the time on hills but at least now the loud, annoying drone is completely gone!

Get the pedal commander or sprint booster.

Let me check what's the dealer price (I'll price it accordingly, but it has 500km right now).

Depends what you are comparing it to, I've had loud exhaust on quite few cars, like STi, M3, M5 etc, compare to those, this doesn't very good because lack of bass, it's very muted raspy sound on the outside, inside, it just drones and vibrate, there's not much tone.

But again, some people may like it, but for me and the wife its not our thing.

Lol don't spend money on that junk. And it wouldn't work on cruise control anyway, which is when he specified his truck hunts for gears. The problem is that it needs more gears.
