Yoshimura  Tri-Oval Full Exhaust


My friend is buying Busa 2004 and he ordered Yoshimura Tri-Oval Full Exhaust System 4-2-1 for the bike.

Our friends said that we must use power commander to gain more HP and if we don't we will degrade the busa original hp!

We are wondering if this is true ? also we are wondering how much power the bike will gain from the system with the power commander and without it?

I don't know that you will need a power commander but you will most likely need to get the factory computer remapped.
