Had the Rush 2'' for 4yrs, even when I did the cams I almost changed them for a little better numbers from a 2-1,,, finally, because I really like them (sound) so much I keep them..

Semi Quiet when U need to be or just steady cruising but they'll sound off really good when U wind her out. all while producing a really deep throaty note at any rpm.

 

I have the Rush on mine and am very happy.

 

I have Rush 2" on my Heritage I like the sound,Nice and deep.My wife has Cycle Shack on her Deluxe not much louder but not as deep of a tone.But they both sound good!
