If you're not looking for LOUD, I suggest waiting till you have at least 5000 miles on your bike. Even the stock pipes deepen and rumble nicely once they're broken in. I wear a 1/2 and a full face helmet. Anyone who says they can't hear the stock exhaust at any speed has other issues. People are so quick to swap out stock parts to be different, they have actually just become one of the crowd. No matter what Harley does stock, has to be changed. It costs nothing to wait a bit... then decide.

picture of cat
Here is a shot of the inside of one of the mufflers from my 2010 heritage softail classic, that is the cat just inside the inlet of the muffler, guess thats why they put the heat sheilds on the mufflers.
The tourers may be different though.
And I will say that with them being in there like that I doubt they will ever get much louder, hell its a wonder the exhaust can even get through there!

You are right, that is a cat. Is it in both mufflers? 06-09, the cat was just in the muffler to the front cylinder.
How to fix? Take a 5/8 in, 18 in long drill and drill three holes through it. Much better flow, nice rumble and you save $300-500 by not buying slipons. Procedure works very well on softails and ststrs. The only way for an inspector to check for the cat, would be to take the muffler off.
fyi...and it still says catylist on the back side of the muffler.

On a cage exhaust with cats, they have a smog pump that works with them. I always heard that you could remove the cats with no problems, but if you removed just the smog pump and left the cats on they would clog very quickly.
Just wondering if the bike cats are completely different than whats on a car, or if there is something on the 2010s like a smog pump.
I guess they have had them on jap bikes for a while now. Anybody know what the difference is between auto and bike cats??
