All done !
It’s much quieter !
I will try and post some sound clips later.

Here is the interior sound clips I took.
Windows up and cycling through all the different modes on the screen.



I took some exterior sound clips but I was outside and the wind noise sort of messed up the quality.
I will try getting those again later toninght.

Hard to really say from phone sound clips, but I think mine is quieter in Quiet, about the same otherwise, but my overall tone is a bit deeper.

I should try getting a soundclip video too.

Nice!!! Been watching for your updates. Sounds like it has a deeper tone. Is that your impression in person?

I was considering these, as they are slightly larger than the Vibrant 1141 Ultra Quiets, so I assume they would be a hair quieter/deeper tone.

Yes, much quieter, and a little deeper tone as well.
Quiet mode is actually quiet now.
Overall I like the results of both the new look and the new quieter deeper sound.

Tonight I am going to try and get a comparison sound clip off one of my other RRs and this one that now has the modified exhaust for comparison.

I took the RR for a walk.
Made 3 recordings,but really all I got was the road noise...

 

[cc1999]

Here’s the comparison videos of stock and new quiet exhaust setup.

With both videos I cycle through all the modes.
‘Both trucks were cold starts.
Note the black truck started up in normal Mode.
‘The 2024 white truck is programmed to start in quiet mode.
‘I did cycle through all modes on both trucks.


Stock truck.



New quiet exhaust setup installed today.

Here is a few pics of the new exhaust with truck down off the lift.
I am really liking the new clean look .

I still need to hit the welds with some high temp black paint to finish it off.

Well, you all convinced me. Just ordered a pair of Vibrant 1141's. My local Midas has an awesome new owner. They are going to take care of modifying the heat shield and adding to it if needed.

I order a 12" version of the same cans that I bought for the 2024 for the 2025 White RR with the topper. The 14" version were a tight squeeze to get them to set squared up like I wanted them.
They might be slightly louder than the 14" cans but in quiet model it is really quiet so I think it will be fine.

I am going to try and get these 3" tips to work on it as well.

Setup the appointment for the other truck for the same time next Monday.

Am I correct in assuming the Vibrant Ultra Quiets are non-directional? I don't see any arrows/markings on them indicating flow direction.

Yep.
Unless you're in the southern hemisphere....
I crack me up.

Got the Vibrant resonators installed today. Initial impressions are as the others have said...Maybe a little more than one step quieter with deeper tone. I seem to appreciate the exhaust tone now so maybe I'll find myself driving in sport or normal as opposed to quiet mode most of the time. I certainly notice the KO3 tire noise more now.

The tiny OEM resonators appear to have packing, but it looks like it is thinly packed fiberglass.
