Alright, so as a guy new to motorcycling (after quite some time convincing my wife...) and with a stock 87, I want to make mods including rejetting, new air filter, AND a new muffler.  Problem is, I don't think my wife will be really impressed if I put on a new muffler that wakes the dead, but want to improve performance.  Of the options that I have seen on threads on this site, what muffler would give the least sound increase with the most performance increase?

Thanks for your help.

spend $250 and get a screaming eagle and a lancers carb LOUD and FAST. i got an iridium plug that i haven't thrown in yet

I like the ideal of "relatively" quiet at idle and louder upon acceleration.  Anyone else use Dyna mufflers?  Are they reasonably easy to install?  Any specific instructions???

I had a Jardien Muffler, and it eventually gave me a headache.  Blued really bad, and was pretty loud at highway speeds.  Sounded great, just too loud for my taste.  I have a HD Sportster muffler that I traded for, with fellow Savage owner Bobo.  I like the deeper sound of the HD muffler, and the chrome is pretty high quality.  Also bought a cheap shield to cover the connection.  The muffler does have to be "adjusted" to make it fit properly, "fit" being the operative word.  one other thing, the muffler tends to point towards the rear brake cable and blacken it with exhaust fumes.  Just keep it wiped regularly, and everything will be fine.
