Stuffing steel wool in the end of a hollow 2 cycle engine expansion chamber might provide a bit of sound deadening for a dirt bike - but it is not gonna work in the Savage Muffler.

Whenever steel wool or glass fiber is used for sound deadening the exhaust does not pass through it - it passes by and the sound waves are scattered into the fibers while the fumes pass on through a bit muffled.  Really effective sound dampening is done by evening out the pressure waves with baffles and resonance chambers....the more the merrier.....and it is a balancing act beween size/weight/function.

An attempt to shove anything up the tailpipe is going to provide the "BANANA UP THE TAILPIPE" trick that Eddy Murphy is famous for.  

If I was going to try and get things less loud....I would either try the method that Serobot proposed by installing an additional baffle core upstream of the muffler - or make an additional baffle that can be attached to the back of the stock muffler.  The RYCA boys have been using stainless strainers from kitches sinks, and I bet you could get a couple of different sizes and stack them together.

In the extreme heat, the pounding from the exhaust pulses, and the corrosive environment of exhaust gases, stainless steel "rusts" too.  It just rusts more slowly than plain carbon steel.

Hi,
I think is 10 times harder to go against the flow!! everybody knows how to get a deeper louder tone just by changing the original muffler with a HD Dyna!! But making a "Silent muffler"!?!?!

Good point.  The stock muffler of the last few years is pretty quiet.

Lots of room for more baffles.

This is what I see inside the muffler. Looks like a waffle design, but apparently not what you are talking about. Would something like this work:  http://www.jpcycles.com/product/4410020   There is room for this. If 1 1/2" outside diameter will fit in muffler. Which means to me 1 5/8". It may not fit past the muffler connector.  Actually up to 6" might fit.

Would it be too much back pressure since it is already a stock muffler?

I went ahead and ordered one, but it cost more to ship than the price itself. I don't know where to get any around here anyway. You can pretty much ride all year down there. I was in the Air Force working on the old Titan II missiles back in the sixties. I also lived in Phoenix for a year. It's still hot whether it's dry heat or not, you still sweat.
