stage 6 exhaust sr50 ... jetting ???

hi everyone, I am thinking of purchasing a stage 6 pro replica exhaust for my aprilia sr50 r, I currently have a technigas pipe on it so not sure if I would need to upjet the carb ?? could someone please help... all replies appreciated.

 

Its not a good exhaust, quality is, ehh welll *beeep*
The Powerband of the engine is pretty wispy.
Its not easy to tweak.
Beside that it sounds horreble, its a screamer with a high sound.
And beside that, on faster setups ( or faster cilinders with a higher rpm powerband )
i have seen silencers blown off.

What Technigas pipe do u have currently? not all the technigas pipes are bad, the quality and performance isn't like yasuni, but for price quality ratio they build nice exhausts.
