New to R3

So I had to take the exhaust apart to check this out. Y
Sorry, should have been more clear.
The 2780 is the size/style K&Ns that will fit under your bearclaw.
I suggest you go to Flipmeister to purchase them and the air temp filter.

Lots of good advice on this forum. I am glad I joined. I could not keep my hands to myself today so I took the exhaust off and sure enough you guys are all correct. The cats are in the mufflers and they are very heavy, and the cross over is empty and light weight. Seems very ass backwards to me. I have ordered the K&N filters and will be looking for the TOR exhaust for a good price. Thanks to all of you for your rapid response.
 
I sliced the front of the stock muffler/cat off and worked all day clearing a hole through the 2 pipes. Decided not to weld a pipe in the opening and just left a hole. Then welded it back together. Not much change in sound, doesn't sound great either. I'm going to try again as a winter project when I don't mind being without it for a few days.
 
I was thinking the same thing. But if I damage the muffler I am buying a new pair anyway. I dont want to screw up the chrome. How far in does the catalyst go? The right side muffler looks like it is pretty deep.

The cat is in the front half of the pipe and is probably 8" long. Which is why I sliced in the front under the cover. It is very intensive and I ended up cutting it out with a hammer and chisel. I only laid out a couple towels on my workbench and had no problems with damage. My drills and hole saws were no match for the cat.
