When it comes to pipes. High level is the way to go. in my opinion anyways.
Termis and DP remus pipes(like mine) are easy to fit.
Sil motor ones look more involved.
Ebay is your freind. Any monster hi level pipes will fit.
Most ebay sellers don't include the brackest and spacers. these are 55 quid from moto rapido tho.
incase you wanna know what a yellow 600 looks like with hi level pipes.
