Do the golf tee mod. There's a vacuum line under the bumper near the exhaust and you can either zip tie it or use some plugs. Look it up in the DIY section.

If you got JB4 no need to do the golf tee mod, you can do it from your steering wheel menu Speedo go to number 4 tacho go to number 5.
Cheers.

The engine is in cold start mode. That's why the exhaust tone is different during start up
