Still have to say these pipes sound great. I don't know what "drone" so many say they hear. Yes, they are bad-ass loud but not the "blat-blat" sound of VTwins.
You can tone them down with the baffles in, but they still are aggressive sounding - which is the whole idea.

I can hear my radio fine wearing a half helmet.

Around town 30-50 mph the sound is especially cool with a lower tone.

Once you hit 70-100+ they are higher pitched. That's the nature of the beast, higher revving and power.

There is no compression or power loss because they are slip-ons and we still have the Cats providing back pressure.

BUT if you don't like loud, these pipes ain't for you. Good luck tweaking them but they are a bad looking, bad sounding pipe - period.
