Car exhaust noise is really becoming a nuisance to some (maybe many) as auto manufacturer's "beef up" the stock vehicle exhausts; some cars are factory equipped with an "exhaust loudness control" (for lack of a better term) and then there are of course after-market exhausts that can be extremely loud and seem to be the ones that attract police.
My sister and brother-in-law have very loud factory-stock cars.
His is a BMW 550i sedan "that boasts a 4.4 liter twin-turbocharged V8 engine with an awesome 445 horsepower and 480 lb-ft of torque." (from BMW)
Hers is a BMW X5 SUV with a 4.4L BMW M Performance TwinPower Turbo V8 engine: 523 horsepower and 553 lb-ft of torque
Both are so loud at full throttle that you can hear them from at least 2 miles away; probably more.
Cadillac has gotten into this as well. The Cadillac dealership gave me a brand new 2021 CTS-V as a loaner car while my XTS was in for service. The CTS-V had a supercharged 6.2L V8 engine with 640 horsepower and 630 lb-ft of torque. It could do 0-60 in under 4 seconds. Whenever floored, the CTS-V was beyond incredibly loud and I was pulled over and ticketed on I-195 while overtaking a slower car. Cadillac dealt with the ticket. The NJ State Trooper was insistent that the exhaust had been modified (based on his "ear" and not a decibel gauge), even though there was less than 200 miles on the car; the new car window sticker was still affixed, and it had a new car dealer license plate on it.
Cops unfortunately mostly go after newly licensed kids on this issue and hit them with tickets (fines) that many cannot afford.

Same displacement, same HP/torque, etc.
