I went with the SE slip-ons. I wanted something that was a little louder than the stockers. They fit the sound level I was looking for.
I just added a SE Heavy Breather Tues and SE Teardrop filter cover.

 

I put Rush 2.0 on my 09 Heritage but after a 4 hour ride my ears were ringing. Pulled out the baffels and the HD Dealer traded them for 1.75, much better.

 

Rush or Cycle Shack. I've always read that Cycle Shack perform the best but I'm unsure of volume.

 

I highly recommend American Custom. They utilize your stock pipe and fit it with their baffles. Depending on how much sound your looking for, they go from from mild to wild. I've been going thru this switch out pipes thing for a month now and have tried Cycle Shacks. Too loud and not deep - annoying IMO. AC's are very deep and as aggressive as you care to go. The bonus is they are very inexpensive. Check out their site:
