Looking to change out exhaust on my 2003 RK. I found a 2 into 1 from a 2010 Street Glide for decent price but wondering if they contain a cat?

Also, would a standard muffler work with the 2 into 1 head pipe? So for instance if I got a single Supertrapp muffler, would it fit onto the 2 into 1 head pipe? Does the head pipe on the 2 into 1 end at the same spot and line up the same way as the stock exhaust on the touring bikes with the 2 into 2?

Appreciate any help you guys can provide.

Edit: looking at some pictures, it appears the muffler on the 2 into 1 setups is definitely longer than the stock mufflers from the 2 into 2. Also, it seems like most people are saying they started putting cats in the headpipes in 2010.

Can someone confirm those two things?

 

First the bad news, the 2010 SG exhaust does have a converter unless it's been removed . Now for the badder news, it won't fit your RK because the frames are different on the two model years.

 

Ahh forgot they changed the frames. Mufflers are interchangeable but not head pipes.

Thanks for the info. That's what I needed. Time for plan b.
