Quiet Mode Exhaust

[HAP]

Does anyone else notice the exhaust intermittently going into normal when driving aground in quiet? I seems like fairly light acceleration makes it change to normal and then back to quiet when the gas is eased up. Just not sure if its expected to stay in quiet when selected?

Yes that’s expected. Probably for engine performance requirement?

You mean it gets louder when you give it throttle? That’s wild.

Just seems to override the quiet mode position of the valve under light moderate acceleration. Like the valve does not stay closed...

It’s normal. Keep your foot light on the throttle. It’s not meant to be a complete silencer of the exhaust at all throttle positions.

Thanks all!

I was checking things the other day and noticed that there is a spring loaded valve on the muffler that the exhaust pressure can overcome allowing it to pass as needed.
Now I understand how and why it gets loader as I originally described.
Thanks for all of the replies.
