I was going to get the 1.75 but a friend of mine at the HD parts department said a lot of guys who get the 1.75's come back a few months later and get the 2". I bought the 2" and love em. Just my two cents worth.

 

I just installed the Rush 1.75 and they are plenty loud for me but they do sound sweet. As someone else posted that when you hold the throttle back it is just a deep rumble but crack the throttle and they come to life!

The only thing I have done thus far is install the slip-ons and when I took the bike out after installing them I was surprised at how much easier the engine seemed to breath (run) and it seemed like I had more HP and TQ. Reading most to the threads on Slip-on I was under the impression it would take 100-200 miles for the ECM to adjust to the new mufflers.

 

I had the 2.25" and they were louder than my Samson's. if you don't like the baffle size you can replace them very simply by removing the screw and pull the old baffle out by using a pair of pliers. They sell replacement baffles in all the sizes from here. http://www.epiflex.com/baffle.html

 

What dealer has the lowest price for the Rush Slip ons?

 

I don't remember how much I paid for mine, but I got them off of Ebay. I got to choose the baffle size I want and they style of exhaust (slashdown, bolony cut, etc). I know the Harley dealership by my house carries them. Or you can go to their website (there's no prices, you'll have to email them) http://www.epiflex.com/

 

I put the RUSH 1.75 slip ons on my 2008 FATBOY and they have a very deep, throaty sound to them until you crack them open, then they are very loud. They seem to keep getting louder over the last few weeks. I thought that maybe it was just me, but my family and friends say that they have gotten louder also. My FATTY runs great with no power commander or anything.

 

I remember reading the same article. Did you ride the bike without the XIED's? Are they worth the $100? I basically have the same setup as you minus the K&N filter (I'm still running the stock AC) and the XIED's. Inquiring minds want to know.

i ran the same setup but with only resistors to replace the 02 sensors and run in open loop mode for about 6 months. poor mans fuel management $1

 

starting the third summer on my 2"'s. they have a deeper sound at lower rpms and idle than the 1 3/4" they are not loud at all till U open it up. they are sweet at crusing speed and putting around..

 

ran across this thread...
1.5" Rush is plenty noisy if you don't want to **** off the neighbors early in the morn. I've had the problem.
Why do you think Rush had to offer now 1.5" ers?????
They're still throatly and deeper than stock but quieter.. take it from experience having to buy optional baffles if you don't get it right the first time... good luck
