As a biker, there is sure a lot of peer pressure to have a louder bike. My s1k has the factory msport straight through akro muffler and a valve system that opens the larger exit, also bypassing the baffles in the 'lunchbox' underneath, at 7k. Meaning it's very quiet until it's being asked to go very fast.

Replacing the cats and lunchbox with headers gives under 1hp on a 220hp bike.

But, every meetup, multiple people are asking "when are you getting a proper exhaust system". Which is basically louder for no other reason but being loud.

I'm amused by vehicles which are very noisy when barely doing anything. Really, almost all cars today have more acceleration than can be used outside racing. Most SUVs and pickup trucks today have better 0-60 times than 1960s muscle cars.

In normal operation today, the power train is not working very hard. Many pickup trucks now have fake engine noise in the cabin generated by the audio system. Not just electrics; gas engine vehicles too. Ford has been doing this since 2015, and most customers do not know it.

I guess this explains why in Japan very few of the motorcycles are loud. It's something I was surprised by when moving here from the US. It seems like in the US most (or perhaps many more) riders are being deliberately antisocial?
