Can anyone help with some feedback on the 2024 392 exhaust boominess on deceleration, around 2k, seems specific to the 2024.
In particular, did it go away when changing to a different exhaust, if so which one?
Cant seem to find any conclusive fix, have read all the posts.

I dont know what you mean by exhaust boominess. The exhaust is louder at deceleration, maybe a garble sound perhaps?

Yes, the Jeep Wrangler Rubicon 392's exhaust has been changed in 2024:
  • Performance H Pipe
    The MRT Street Race H Pipe replaces the stock X pipe and resonator, giving the 392 a deeper tone and more horsepower. The H pipe also allows you to control the sound level with the factory exhaust valve system.

I think the MRT H Pipe is aftermarket and can be installed on any 392 but isn't stock on any of them.

Some of the boominess (drone?) I experienced was from the active noise cancellation. If you disconnect the microphones in the rollbar above the back seat near the speakers (need to remove the plastic trim) it disables ANC.

We just need a way to disable the annoying 4cyl mode and the horrible, augmented sound it makes when in that made...

I deserved that... :)

Ok so I only find it on the 2024, and its a strong resonance when decelerating and hitting 2000rpm, so only in the lowish rev range not above 3000rpm. I know the 2024 has dual pane glass in the front windows, and wondering if this causes it.

Will try the ANC trick, although I have read elsewhere in the forums that it doesn't do anything.
Also going to try the Magnaflow street exhaust., will give feedback on this issue as I know others have experienced this as well.
