The Valvetronic system
allows you to switch between
being quiet and being loud with the push of a button via remote controller
Who invented Valvetronic? BMW
First introduced by BMW on the 316ti compact in 2001, Valvetronic has since been added to many of BMW’s engines. The first application of this technology in a turbocharged engine was the N55 engine.
Are Valvetronic exhausts good?
It’s awesome having the ability to be loud when you want it to be loud or quiet when you want it to be quiet.
