, I have an 1100 with a Kuryakyn hypercharger and a cobra exhaust. I personally love my set up. She has that nice deep rumble without being too loud, and I really like the look of the hypercharger, like having a blower on a hot-rod. The horsepower benefits are debatable, but from what I've read running it on a dyno doesn't do it justice since there would need to be air flowing over it at speed.
Regardless of what intake you choose, I agree with @jhennly
, you're going to have to open up the exhaust.
