I don't want to decat it, but with the cat and a baffled silence it is whisper quiet. Keeping the cat and removing the db killer would hopefully be a nice balance, if its too loud, back in the db killer goes.
I'd bet even if you took the whole can off with the cat in place,it would still be quiet. Taking out the baffles will probably make little difference if you keep the cat. Try it first and see.
I suspect similar. On the GSXS the OE end can is almost straight through and on YouTube of aftermarket cans with the cat in place the noise difference is barely noticeable. So I think the silencing happens in the cat.
Similar to the 690 I started mine with no can on at all and it sounded stock pretty much.

People used to ditch the can and just fit a short tailpipe on BMW GS's and, iirc, they still met the decibel rules and regs, just sounded a bit more fruity. Fuelling didn't need changing either. I think the cat is quite a labyrinth internally.
I think Rock Burner has his Rockster set up like this. I have the Y-rohr and a straight through Remus. On the K12, the cat is in the endcan, thats why it weighs about 20kg and gets red hot at night.

Realised i've just gone past 8k on the X-ADV. So, its time to treat the old girl to new oil and filters this weekend! Over 4k miles on it now. WTF keeps a bike for 4k miles!

Who are you and why have you hacked Terrapin's account?

lol I did it trim it flush just after the photo
Which plug set is that? it's a massive plug for a small hole....
Stop n go kit. I've had it for man years and ist bailed me out quite a few times, on a car too. But the downside is the plugs are fiddly and easily fail if you dont get them just right and with enough lube on them.

I did a DCT reset on the bike as being an adaptive gearbox and and me pootling through London's 20mph the gearbox had become slow to change down and was changing up too quickly and was sounding like a toolbox falling down the stairs when it was changing gears. Amazing how its been transformed to a nice smooth gear changing bike with the flick of a few switches!

Still rolling with the rope plug at the moment. Pressure is holding and someone seems to have done 103mph on it on Sunday according to the Sat Nav. I must have been having a coffee at that point.

I think the rope ones are much easier than the stop n go. Also there's no glue involved in a stop n go mushroom, which i've always found a bit disconcerting, but I've never had one deflate.
But then
