I know a lot of people will say no, but my experience is different.
Back in the early '80's I rode an 1981 GPz550. Ended up putting a Kerker exhaust on it and installed one of Kerker's racing baffles. It was louder although not obnoxiously loud, and sounded more like a Z1 1000, much deeper note to it.
I remember coming up behind the blue hairs in their Cadillacs/Buicks and getting a chuckle out of them searching their mirrors for what was making the sound. They heard me coming up from behind them which a lot of people claim is BS. I know differently.
My opinion, and only mine is, an HD with LOUD pipes sounds like a crapped out POS farm tractor.
