r1100s muffler on a r1100r?

[cncltd1973]

Hello All,
My latest acquisition is a '00 r1100r that I am cleaning up. I don't use aftermarket parts as a rule, using only parts that factory engineers have access to. And by 'cleaning up', I mean eliminating cluttered lines and simplifying functions without compromising results. Basically, trying to create the prototype the design department wanted before the other departments put their 2 cents on it.
All that being said, whoever had the bike before me eliminated the cat and put an aftermarket muffler on. So I'm looking at mufflers from different models, and looking at alternative locations to install on the r1100r, and notice the bike would look much better if a boxy muffler was in the space between the centerstand and the drivetrain, with dual tips that end before the rear wheel. As it turns out, the r1100s muffler looks like it fits this purpose perfectly, but I'm not sure if the dimensions are too large for the space. Online searches turn up nothing, so I'm hoping someone here has some advice or direction.
Thanks,
Josh

Not sure the r1100s mufflers would work, they are single pipe in and I think each one is different internally, the cat for the r1100s sits above the centerstand and is single pipe out.

It's not impossible but having looked hard at doing just this can tell you there's a couple of tall pole problems to overcome and then you're looking at a passenger pillion that's too high and you'll have to abandon the stock rear subframe in the end (not enough room between it and rear tire)...at such point it's easier to change up an R1100S than an R1100R but that's just my opinion, best of luck....
