2Brothers 4-into-1 - Custom job?

[neversaydie]

Hello XX forum,

I bought a 97 XX (yahoo!) which came with an aftermarket 2 Brothers exhaust system. The single muffler is carbon fiber and the system is a 4 into 1. My qustion is, did 2Brothers sell this muffler system at one time or is the header/muffler system a custom job? I can't find any reference to a 2bros 4-1 system after a couple google searches :icon_wall:

And if this is a custom muffler setup, is a dyno tune and jetting the only decent method of getting the fueling correct?

Thanks much! Alan

Check this link: Here you go? Do the search for Honda sportbikes and in the dropdown, pick CBR1100XX.

Alan, yes 2-bros use to make a full system in both the config you have and a shotgun config. All they make now are slipons. You may be able to call them to get the specs for proper jetting.

It would be interesting to see if you could actually buy one of those systems.
