I have a 2012 Harley trike and looking for some slip-ons. The more I research the more confused I get. I would like to pickup a little horsepower and a deeper growl. Any input or suggestions would be appreciated.

I put Vance & Hines "Classic Slip-Ons" on my 2012. These have a slash-cut end with chrome billet end caps. Although designed for pre-09 bikes (without a cat), they bolt right up and have a very deep, throaty rumble. I'm very happy with them. You can get them on that well-known auction site for $250 with free shipping.

We put Rush slip-ons on the 09, and Reinhardts on the 11. Neither required any major fuel management changes, only a re-map. Both have a deeper rumble without being obnoxious.
Besides installing the slip-ons is there anything else I need to do?
You need round slip ons, I recommend Vance Hines they sound great and looks great.
My understanding is as follows:
- Muffler change, stock header, stock air cleaner - ECM recalibration / remap not needed.
- Muffler change, new performance header, stock air cleaner - ECM recalibration / remap not needed but suggested.
- Muffler change, new performance header, high-flow air cleaner - ECM recalibration / remap required.
My 2cents
If you like loud - get Rhinharts - obnoxiously loud - I won't ride anywhere near someone with them on.
Dealer install cost - don't know since the dealer installed my H-D Fatshotz for free. They are completely tuneable.
As someone earlier said - install yourself - very very easy - if you have the tools and room.
Keep your original pipes for when the government decides to really crack down on illegal ones.
I don't think oval mufflers will look very good under round cutouts.
If I didn't have the Fatshotz, I would go with the V&H - I like the distinctive looks better. Don't know how they sound since no one in my chapter has a set.
I'll assume they sound like any other aftermarket pipe.
Only a few in my chapter have Rhineharts, but a lot either have stock pipes or any one of the Screaming Eagles sets.
I love my Super Trapp Stouts 4 inch..Nice deep sound ..Not loud at all..
Good Luck!!
