Going from the stock exhaust to the V&H...yes it SEEMS insane loud. Whether or not it actually is insane loud compared to say a HD Sportster...I don't know. But the rumble is awesome and it looks great compared to the stock exhaust. I just put mine on a few weeks ago. Debated taking it back off after the first ride but ultimately decided to keep it on.
I'm curious to hear what others with the V&H think too, but from my perspective I would say yeah it mellows a little bit around 50-60 mph. Up around 70 mph and above when the revs are running higher it definitely does not feel that way though.Nice. So let me ask you this. When you are shifting gears of course it's gonna be loud. But when you are in 6th gear cruising at 60mph does it mellow out? Does the bike behind just get blasted with sound at cruising speeds?
