Strangely enough, MArk, that's enough to muffle the sound a bit.
If you ever have to remove a slipon for some reason, go ahead and crank the bike for a minute and let it idle without the the midpipe and slipon on. After the nieghbors stop beating on you, you can imagine that same noise, very slightly reduced, but coming out of the back of the bike.
I'm no expert on exhaust systems, I've just heard enough engines with straight pipes, or no pipe...........
There's actually quite a few localities with db level laws, but not many enforce them often. Usually they spring up after a 'problem' has developed.
(Kids with megawatt stereos cruising, cruiser or squid bikes on parade, etc.)
It's disgusting that such laws are needed, but some people are arseholes!
(And they ruin it for the rest of us!)
My Holeshot pipe is pretty loud. In urban areas I keep the revs down.
I would like to hear my Bandit from the vantage point of somebody NOT riding it. I was surprised at how loud the STOCK exhaust was on my DR650 when I was following my Brother who was riding it.
I think he was wringing it out though.......
(The awesome sound of 34 ponies......)
