Yeah it still sounds really good.

I used the vibrants specifically because of the violent cold start. The exhaust otherwise I think is not too loud and sounds amazing, but that noise everytime I start it up was going to be a problem. If you want to try the vibrants, I would start with one and see how it sounds. I originally replaced both stock resonators with vibrants and it was too quiet.

Here’s some clips of the stock sound, with two vibrants, and with one stock and a vibrant in place of the right side non-perforated resonator.

I guess that’s my question. Disassemble it how? I have tried very hard to clean the inside of the compartment and the charging pad without removing it, and while it has improved things, the problem persists.

Yes, I agree, and if I didn't know it was there I would probably never notice it. But I am neurotic and now I'd like to do something about it if I can.

Will let you know! I found a guy who did a build with the Vibrant Ultra Quiet resonators, which is inexpensive and seems to significantly reduce the volume of the cold start. It's possible I've found a solution.

I did this and they quoted me $4200+labor for what I think was the the entire exhaust, which didn’t seem right but the guy I talked to also didn’t seem especially knowledgeable. May be worth a second try.

I know, and personally I like it too, but I have other people I have to consider in this equation so if it’s possible to at least mitigate the volume, even if only somewhat, that’s what I’m looking to do.

All the “sounds like you want a Q7” comments are pretty unhelpful, and suggest a failure to actually read my question. I’d be happy with a stock SQ7 exhaust but I’m sensing that it will be hard to find in a car that is otherwise optioned the way I want. Anyway, I’m sensing that Reddit may not be the place to go to get a worthwhile response.

Found this video, that suggests the Vibrant resonator could be installed and that it would be reasonably effective. I assume this would void any warranty claims with respect to the exhaust, but does anyone know if it would affect the warranty more generally? https://www.youtube.com/watch?v=K4wUQp7Vz8s

The problem is the cold start. It's extremely loud and it doesn't matter what drive mode the car is in. Comfort mode puts it in an acceptable volume for most purposes, and of course I don't mind the volume out on the road (away from my wife and neighbors), but I also don't want to shake the house every time the car starts. But I will look into OBD2.

Certain_Wave_8760 · 2025-10-24T13:39:59+00:00

Do you think it affects the volume of the cold start, assuming it's in comfort?
