My question is that silencer of my bike is in moderate condition and i am planning to change it in a month but there is a query in my mind that whether to go for a stock exhaust system or a free flow exhaust system.Please guide me as soon as possible...........................
Important things -:
Engine work is re-done in april and completed 1500+ km/h.
Installed a k & n r 1060 free flow air filter.
Currently top speed is 115km/h max.
