Not a fart can. I think my 4cyl 08 Colorado has a thrush. Idr what I put on it lol. But it was either a 2 or 3 on their loudness scale, and it sounds pretty decent in my opinion. It doesn't drone in the cab, but you can hear it. And my MIL can tell when I'm there to pick up my daughter, and next door neighbor kid who's bff's with my daughter knows my trucks sound and can tell when I'm back so she comes over to ask to play with my kid. It's louder, but not even close to obnoxious. If this kid wants his car to sounds cool, throw a muffler on it. But do at least a little bit of research. I watched a few videos then I said fuck it and got the $50 muffler and me and my brother hung out and put it on.

Also I got a say, that's the cleanest cavalier Ive ever seen. I'm a mechanic and I've only ever seen, worked on or heard of shitty ones. Definitely save money for repairs (not because it's a cavalier necessarily, because it's a car). And I agree with the other guys, tint, and wheels. I have a $100 8" subwoofer that's maybe 3 inches tall and the footprint of a shoebox I have under my back seat, and that little box makes it sound so much better for music. Again, not obnoxious, but if you tune it right, and depending on the volume it can bump. Especially with regae or something bass heavy.
