Completely tool-less
Completely tool-less, 10 minutes installation, fully plug and play, no check engine light, no stored soft codes. Now with the new functionality, it's even better!

Best valve controller!
Brilliant product!! Installation time is 2-3 minutes per side and it will definitely have a deeper sound than the factory system. What I like the most is that it provides the same sound in all modes (not just sport or sport+).
I am satisfied and would recommend it to anyone looking for a valve controller.
