This sound of the exhaust is great

especially without the DB killer
i saved around 5.5 kg (12.1 lb) by fitting this exhaust (Titanium link Pipe + Gp Ultimate Carbon Can)
The bike now fishtails under power in the low gears, it never did that b4

the combination of less weight and a lot more power does the business and this is without PC5 or airfilter mods
Thanks Austin Racing for such a nice product, especially Mr. Rich who helped me with my order and questions
Soon i'll post some video clips of it
