I have a road rage on my FXR, with the “quiet” baffle. I really like the sound, but it’s just about as loud as I want (or can take for any length of time). So I've been thinking about getting one for my Low Rider S. Wondering if I put one on my LRS with the 110 motor, any idea if will it be much louder then the 80 EVO motor on my FXR?

 

Not necessarily. I would imagine that they would have different header dimensions (diameter) and baffle compositions. That might not mean louder.

I would think YouTube would be your friend here because I doubt that a lot of the guys that have them on a lrs also have a fxr like you to compare. And after all most will have one bike and it's all opinionated.

 

bore diameter will have an effect on sound but its usually pitch. plus its a wider pulse between strokes so if i had to guess it will be a little deeper, just as loud, and maybe move a little more air. i dont think header pipes are any difference in size though.

 

 

i have the rr3 with the 117 kit its not too loud. the fatcats ive had on previous bikes were louder

 

 

I think they are just higher up based on sound. I have been researching for the last 2 months and the road rage has almost identical numbers to even the two brothers exhaust. Biggest difference is sound. It's a little higher pitched than I like so I didn't go with it. But to each their own

 

 

 

With a larger bore, it should offer a lower frequency exhaust note. Everything else being the same, that is.
