I know it's not exactly what you want to hear, but I would think it would fit because of what I did:
I really loved the look of the R77 carbon can, so I talked with Yoshimura, and ordered a header and midpipe for my 2005 LE and then ordered the R77 Carbon muffler for a 08/09, basically piecing together my full system. So that said, it should work for you, but maybe call Yosh or Email them just to be safe! GOOD LUCK!!!!!
