Modifying '06 Busa to fit an '08 exhaust???

[Chrome lover]

I have a 4 into 1 Headers with spring loaded slip-on mids. I just bought Hot Bodies megaphone exhaust, but its for an '08 Busa. I want to run two exhausts. The pipes on my bike now are too big for the slip ons, what can I do other than buying new pipes?

If Im understanding you correctly you could have a sleeve inserted into your pipes and have them tapered down to the size you need it to be.

Would be easy for a muffler shop to do.

What about my mid which goes 4 into 1? Do i need to buy a new mid? Because this is definitely not a stock exhaust system...
