As a collector of some vintage cars, I am on the side of those that prefer stock exhaust systems. There is no real need to put a huge exhaust pipe (4 inches or above) on unless it is designed to be at the track only. There is a difference between a healthy factory growl of an American muscle car/European sports car and one that was modified to be as loud as it can. Also one does not need to go around needlessly zooming the engine to get attention. Trust me, you will get plenty of attention just being in an older car that is uncommon to come across on the road. Mine are used to do cruises, not to race others on the street. All of my cars retain the stock exhaust systems and are in tune when I drive them. If you want the car hobby to continue, one has to be respectful of others or the laws will change against you.
Personally, I hate “fart pipes” on Japanese cars, as they seem to be the worst offenders for noise rules. Those are basically huge mufflers that are put on to make the car sound if it is ripping a good one while driving. I have seen police enforce noise laws on them and fully support that action when warranted.
I'm not a fan of fart cans or over massively oversized exhausts on NA engine. A single great big 3 or 4 inch pipe might make sense on a big single turbo engine, because they'll reduce back pressure but turbos make things quieter anyways. Typically an NA engine requires a big of back pressure for scavenging exhaust gases, bigger isn't inherently better.
Loud is relative, modified cars should be held to the same standards bikes are. That's still loud but with an upper limit. Bikes are typically held to a different (more lax) standard than cars are (from the factory), I've got no problem allowing hot rods and bikes to be louder than an unmodified factory stock car. There's simply not that many of them out there to make a huge difference and strictly enforcing limits amounts to a huge waste of police manpower that could be better invested dealing with actual concerns.
