Active exhaust sound on start up

[bmbl-bee]

The exhaust isn't loud on startup because of the exhaust valves. It's loud due to the PCM cold start routine. No, it's not possible to have that all the time and that's why others are recommending other ways for you to get your volume fix

That explains it. Thought there may be a way to bypass the valves to fully open. Thanks.

In your software, you can program your "quiet start" to start up in quiet mode between certain hours. The quiet hours I set up are between 10pm - 7A.
