You'll need to somehow fab an inlet pipe to fit the larger exhaust pipe inlets on the 54mm muffler. I've had both on my 999, the Termignoni slip on muffler sounds tons better. I have no idea why, probably the use of the full exhaust w/ the 54mm muffler muffle cut the sound down. However a Termignoni slip on muffler will fit w/o any issue's...and w/o a doubt sound much better.

The muffler is made to fit 54mm pipes. The factory ones are definitely smaller. You would have to have someone cut and weld some piping onto your stock pipes to make it fit. I don't know how much bigger they need to be, but I imagine flaring some pipe and welding it on might be enough. And no pipes were different for any of the XX9 bikes, all the same.

The link pipe is designed to be the same size as the stock pipes without the catalytic convertor. It is not enlarged. The ONLY pipes that will work without modification are the original 54mm pipes that came with the exhaust can. Part number 96433403B is the full kit. Those are the only pipes that work. If you take your stock pipes to a custom exhaust shop I am sure they can figure out making something that will fit it for you. Cost, I am not sure what that would be. I would imagine it would take at least 2-3 hours of labor, maybe more.

Ideally you would want the cat removed from the link pipe bc the exhaust can does not have one. I have a couple link pipes that I modified that fit regular sump motors. If you want one of those you I could sell you one. Or you could modify the one you have. Up to you. Just let me know if you would like one.
And it also would be ideal to have a Power Commander to adjust the air/fuel ratio bc without the cats the exhaust will probably lean the mixture a little bit.
You could reuse the exhaust gaskets, just put some liquid exhaust sealant on them when you reinstall (any auto parts store will have that). The exhaust can was designed to have pipes slip inside it, so there are no gaskets at the can connection. Just make sure it has a good fit and you won't have any leaks.

$80 for the pipe. Shipping probably wont be cheap bc it is an odd shape. You could easily have a shop cut off the cat from the middle of the pipe and weld in a piece of pipe to fill the gap. That's all I had done. They just have to put a piece in that is the same length. I would do it bc one cylinder will be running hotter bc of the different back pressure.

Cool, good luck! You will have a much better sounding machine when it is done! Maybe have the pipes coated after all is done to make them look perfect?

Sell the Termignoni 54mm muffler then pick up a slip on.....it will sound loads better and the system work look so jury-rigged. To get any sound you need to get that cat out of there.
Be patient. peruse Ebay...IIRC BursiEvolution is selling a catless horizontal pipe for the 999/749..cheap. Grab a slip on muffler and the world is your oyster!
