My dog is kind of a baby, a big 90lb furry baby that hates car rides. She hates my girlfriends Tiguan but will fall asleep in my rear seat deleted car. I have a Catted downpipe, MBRP catback and motor mounts so it’s pretty loud. I’ve never seen her fall asleep in any other car. My girlfriend also hates my exhaust but falls asleep in it too. As said above, long term exposure to higher db wouldn’t be good for little ones. I think the Thermal CBE would be the money spot.
