The biggest bang for the buck mods are airbox/filter mods, jetting the BS40 correctly or replace with a VM or PWK carb, a better flowing muffler, and a cam swap. All of that will get you around 10 to 12 hp over stock for not much money spent. Power gains above that point will get more expensive and the gains are smaller for each mod.

The Emgo I posted is the cheapest alternative....it is too loud as it comes from the factory, however it is easily modified.

The Harley Dyna is a great muffler for a stock engine.  It has a nice sound that is a bit louder than the stock muffler and it actually sounds like a motorcycle.  Out of curiosity I put one on my modified bike recently, and it definitely slowed the bike down a bit.  I have used a hole saw and cut the stock baffle system out and installed one that is a larger diameter and has more holes and therefore is less restrictive, and that helps get more flow for engines that are modified.

The muffler that DragBikeMike is great for modified engines and is within the fabrication abilities of most folks, and it looks good on the Savage.

For my Cafe' bike I wanted a smaller muffler and I used an Emgo chrome megaphone and built my own interior.  It has gone through a few iterations and it works well for the way I ride.  It looks good, is small and light, it is not too loud and it flows much better than a DYNA.  It likely is a little bit restrictive - but most of my rides are on curvy roads and I seldom need more than half throttle on a days ride.

The core is currently straight through, and I have wrapped the end section with stainless shavings from a brake rotor I cut down.

(The website is currently giving me fits about posting photos...I will post some photos another day).
