Just a theory but I'm also 100% sure it's true

There is a house in my neighborhood with your picturesque McMansion short king that has a white Chevy Tahoe with the loud muffler setup! As annoying as it is on performance cars, I kinda get it. But in a family SUV? Dumbest thing I’ve ever seen. And he revs it in front of middle school kids waiting for the bus to boot. What a sad little man.

Yea well those performance cars are also not street legal lol

Though I see a reason in there

If it’s on an SUV… Fuck off with your loud shit bro.

Also just loudness is nasty. The sound itself must be nice. If it’s not an H pipe I don’t want to hear that shit.

Deleting cats can be illegal depending on state but trust me there are plenty of legal, loud exhausts
Well I guess it depends on the area. Afaik, in Romania where I live, if it goes over a certain db count at a certain RPM it’s illegal no matter what.
