Got 'em, like 'em. Was told by Fuelmoto2.5's don't creat enough back pressure. Got 2.25's. Pretty loud.

 

I have RUSH 2.0 slash UP muffs on my '08 UC. Love the sound and the look.

Now, according to my service department at my dealership, you can use UP TO 2.0 inch baffles without any mods to your bike. No changes are necessary to your intake, no race tuner, etc. Go to 2.25" baffles and expect problems.

So, I took their advice and love the muffs. Good equipment, nice chrome, a good value, imho.

 

Noise or performance? Want noise then ditch the baffles and get obnoxious. With stock head pipes Rush recommended 1.75 in the left and 2.25 in the right for the muffler with the TMax/Intake combo. Plan on getting different headers in the future if you plan on using OE headers with your Rush mufflers. My nutz are deep roasted after commuting 5 days a week on I-95 in stop and go traffic with the stock headers and if I could go back in time I would have done SuperTrapp 2:1 instead.

 

Sounds like the 2.0 is what i would want,i'm not into making mods.

 

I'm haven't been very impressed with my Rush slipons. The 2.25" slash cuts weren't loud enough (I could still hear the damn 5th gear whine). So I ordered a set of 2.50" baffles and the sound is more to my liking (louder), but now I have alot more decel popping. I had the bike dyno'ed and they got some of it out, but it's still pretty bad.

I'm probably going to ditch the Rush and go with some true duals ... either V&H or Rineharts.

 

My dealer told me that they had some problems with SuperTrapp and they would not stand behind the product.

 

Got the 2.0" on my '07 RKCustom and I'm very happy with them. Great sound...loud enough for me...and didn't have to make any mods. Planning on doing full stage 1 in the near future. But for now I'm happy.

 

Have the 2" straight cuton my 97 Ultra, love the sound, very very deep and gets plenty throaty when I get on the throttle!

 

Have the rush slip ons on my 07 street glide and really like them. I was torn between the rush and v&h ovals. The rush seem to be a great bang for the buck pipe.

 

I have the 2.5 mufflers. I ran them for a while with the stock headers and was not happy. I added Vance and HinesDresser Duals and like the combination very much. The one thing I don't care for is they appear to be single walled and gold at the point where they meet the header pipe. Thank you to Blue Job.

If I had to do it again I would not go with the Rush headers and would have Vance and Hines Classic slip on muffles (orany Vance and Hines muffler)along with the Vance and Hine Dresser Duals
