The system worked reasonably well for the first 6 months. I could cycle the exhaust open and closed 19 times out of 20. However, after six months, the vacuum control box just stopped working. I've checked power to the box and it has a good 12v supply. No issues there. I would be open to returning but there is no possible way of doing so.

Easy installation, excellent sound and the possibility for my vehicle to drive without restrictions.

Good soundQuality build

I buy two, the difference between open and closed valve is almost the same sound
