Just put some Rush pipes on my 2012 custom 1200. Went with the 2" baffle and a Screamin eagle air intake. Had my computer re-maped. I realy like how it sounds. It's a lot louder than stock but now it sounds like a Harley. Runs great!

 

Put some Rush pipes on my 2012 Sportster 1200 custom. Went with the 2" baffle and aded a screamin eagle air intake. Had my computer re-maped. It's a lot louder but sounds great to me. Runs good and sounds like a Harley.

 

V&H Straightshots. Great sound, a bit louder, and a noticeable performance boost with no ECM tweaking.

Pretty happy with 'em.

 

Went w black SE slip ons. Not awful loud but definitely deeper growl than stock. Sounds nice to me without turning off the neighbors. Performance is great, but I'm sure not a 6 hp jump if that's what you're looking for. For me mostly look and sound, went w 1200 over 883 for the go factor. No ECM changes needed. Love mine..
