Dealer is wrong. Had them on my R3 until the Jar install last month. You will need to change the tune. I think they put the 55 tune, it may be different now. Took about an hour to install at the dealer. Not much louder, but more power. Have them install the idle fix tune as well. That should not be a charge if under warranty.
Good Luck!!!!!!!!!!!!!!!!!

My personnal feedback :
The Bypass is not designed to be used with stock mufflers and there is no tune available for that set up.
Anyway, Bypass + stock pipes works without problem.
I've never understood why so much people uses that set up because the stock mufflers are much more restrictive than the cat.
I've road tested the two combinaisons :
Bypass + stock muffler
Cat + aftermarket mufflers (Tor's and Maddogs)
The sound is about the same for both with the tor's. (A little bit Louder and deep with the Maddogs).
About performances, the cat + performance mufflers is much more pleasant to ride, with more torque in the bottom range than the other setup with better high end.
Good point : A specific Triumph tune is available for that (everybody doesn't want to go for a PC III or a tuneboy....)
I still believe that bypass + stock mufflers is a nonsense and that your dealer is not as idiot as he seems Rude dog !
Only my two cents........

I found a big difference in performance with the stock mufflers and the cat bypass and a slightly crisper exhaust note. There is a Triumph tune for that available.

What is the number of that Triumph factory tune for the stock silencers with cat box removed ? :?:

This is a real memory test for me Jack but I think it was 20054 that worked, dealer installed before Tuneboy came out.

There are tunes available for Tuneboy or PC III for that setup.
But, I haven't found a specific factory tune for by-pass with stock silencers :
