i run a cat free race exhaust on my bike with no db killer. my fathers bike also runs a cat free full system and has been remapped a increase of torque by 6% throughout the ranfe and a increase of 5.5bhp

Quite a leap to jump from a rumour that the Benelli uses an old R6 engine to believing that the bike can be plugged in to Kawa diagnostics and remapped and that it will take a whole Kawa exhaust system. Also I was commenting on a Chinese exhaust system where the pipe was hacked and a candleabra that looked like it was solen from a Synagogue was welded on = power or torque boost unlikely.

Pete, read that thing about early oil change just in case of factory oil shavings is probably uncessary on most bikes, but a worthwhile insurance policy with any China bike.
