Yoshimura RS3

[kawasuki]

G'day all, i am thinking about purchasing a pair of stainless bolt on Yoshimura RS3's, my 2001 Busa has been remapped, got a highflow airbox and TRE, just want to know what sort of tuning may or may not need to be done after instillation, can the stock ECU be tuned to suit or would i be better off getting a PC3?
Since that the fuel has been remapped can i just install the pipes and ride as is?
Any and all info will be very much appreciated.
Cheers
Stay upright

Mate u would be better off getting a new system then use a PC.
