I have reviewed several papers on the Hartman mod to the stock LS650 muffler.  I like the idea of having a good flowing muffler that doesn't break the sound barrier.  While 96Db is pretty loud it is far quieter than 101Db.  I also think it's really cool to have a stock looking sleeper rod.  Have any of you Savage Beasts performed the Hartman mod?  What is your seat of the pants estimate on noise level?  Does it wake the dead or just pat them softly and ask them to roll over?  Any gut feeling on extra steam at the throttle?

Not to mention the considerable weight loss by tossing the stock exhaust system, using a Harley muffler, and making a new head pipe with single wall pipe. The factory system is a lot heavier than it looks.

The Jardine should not be allowed to use "muffler" in their description....they should be called Jardine Noise Makers.

There are muffler options that are much better at allowing better flow without excessive noise.  The used Harley DYNA is the cheapest and not all that difficult to find a good one on eBay.  The EMGO short cone is available on eBay or from RYCA - it is a horrendous noisemaker unless you buy the insert that RYCA makes.  The Supertrapp is nice, a bit expensive, and a tad bit louder than I like.....but it is not excessively loud.  Cone Engineering makes some Quiet Core mufflers that are well built and can be adapted to the Savage.  

You might even be able to adapt something like this:
