I do have some videos I posted of the sound last month if you want to listen to it. I'll post them on here as well but I may be a bit exaggerating but it isn't that quiet either when stopped at stop lights
That is true, I'm defiantly probably jumping to conclusions as I just want to get it quieted down at least a little bit.
Guessing a bit here....but that doesnt sound like valves to me. More like a purge valve.
