if the previous owner did an ac Im guessing he must have already did something to the tune. if not you can go with xied's to accommodate a new full exhaust system then upgrade tune later

 

I got Cycle Shack slipons. Nice sound for about $150. If you're looking for more performance than go for a full system.

 

You are good to go with the 2.00 Rush Slip-ons.
I have them on my 2011 StreetBob and love them.
You won't want anything else!!

 

if you like the look of your stock exhaust and just wont be happy with a different look the 2' rush slip ons might fit the bill.
However if you are planning any mods beyond just slip ons, air cleaner and EFI Id get a set of full exhaust pipes. I have always just replaced my stock pipes with aftermarket. I ran a set of cycle shack mufflers on my first harley . I was happy with them till I replaced the whole exhaust system. A new exhaust just makes it a whole different machine. The pipes I currently run are rated from 96 ci up to 113 ci . I cant imagine ever needing anything more. they look great , sound great, and run great.

 

While a full system will deliver more in the performance and probably sound, I decided to be real cheap and buy a set of Rush slipons with 1.75" baffles used. I love the sound, really like the performance, and since I got them really cheap ($75) I figure if I ever want to upgrade to a full pipe, I can always sell them for at least what I paid for them. I do not regret getting them.

You might want to consider that route.

 

slip ons for 75 bucks ... you did get a good deal.

 

I got them from someone on one of the forums. I just decide what I want to get and then sit back and watch and wait for someone to sell what I'm looking for on the cheap. That's how I've done most of my mods.

 

Have you looked at Big City Thunder baffles? I have a friend with the SE slipons and he changed to BCT baffles. They do sound good.
