Slap in some cams and have the heads milled and ported to match the cams. The added compression along with the extra air supplied to the engine by higher lift and longer duration cams will also deepen and add volume to the exhaust note....also cheaper than a new engine.

check out RB Racing - google it- look at their Orca motors. up to 143" I believe. add turbo if you want. sky's the limit. set your own land speed records 
BTW depending on what motor and the rated output, you may need a new transmission (baker), drive belt and pulleys, primary, clutch and associated. maybe some frame reinforcing along with suspension. what the hell it's only money. ;p

S&S makes a 124" for softails. They also have a 143" for touring, not sure if it's available for softails. If all you are after is volume a set of loud pipes would be much cheaper than a new engine (motors are electric).

will all that mean my bike is in the shop for repairs all the time?

Plenty of strong running and dependable 96" and 103" bikes out there. Whether or not it's "good enough" is up to the individual. Like LA Dog said..."the sky is the limit". Or as in my case the $$ is the limit. Frank Drago at Dragos Bike Works builds some bad *** turbo bikes too.

Issues start when people who don't know what they want start throwing in bigger cams, bumping up the compression, oversized throttle bodies & injectors, etc. while trying to get Internet breaking numbers on the dyno.
As mentioned above, there is also the need to upgrade a lot more than just dropping in a motor. If you don't, you will not only be a waste of an engine, the bike will be in the shop more than it will be on the road.
If I had to do it all over again, I would of just kept the bike 100% stock instead of having the 95" big bore kit installed before delivery (root of all engine issues due to poor installation) and bought a couple of sportbikes.

Honestly I just want it to cause an earthquake when fired up 
I dont care about dyno numbers I just didnt know if I needed to go with more cubes with a good set of pipes, or stay with the 103 and have to do a bunch of mods to it, or both? Whatever makes the beast sound come out more
I have money for either way but I dont want to have to keep going to the shop after its all done. I dont race it or anything like that, just a casual rider, barhopper type.
