I just got the rc slip ons put on my bike. The dealer told me the next step is, the air cleaner, fuel pak and the headers. I have a 2012 rgc and I never had heat issues as a rider on it but my wife complains about the heat around her right ankle.
Doing some research on this made me confused very much.
Should I just get the fuel And the cleaner or the whole thing?
If it is going to make it just louder, I would rather to spend my money on something else like the daymakers. )
I have read people saying that the slip on Ad ons are just for the tone of the sound and it does not have any performance gains without the stage one. I went ahead and did it I say bs to those people, my bike pulls much stronger now.
I have never had slip ons alone change the performance of any of my HD's that had the catalytic's in the header, the restriction is still there, the cats are in the head pipe, just changes sound. If it feels better to you, then more power to you.
As for the heat on her ankle, you need to get the bike tuned properly, AND get rid of the catalytic to cool the bike down, and it will also have more power and "should" get better mileage depending on the tune.
Just my $0.02
I recently traded in my old bike for a new one, and forgot how friggin hot these bikes are in stock form....
I am not advising it but you could always try the method the BMW guys are fond of
