Melbourne GG rider in need of Exhaust help"

[GASGAS450]

Hi All, jumped into a 2009 EC450 a few weeks back, awesome bike, but she's a bit on the loud side.. Its ok on Enduro tracks, but I live in "Greeny" territory, so after some help to shut the thing up.

I have repacked the og muffler, slightly crushed down the baffle and re worked the hole pattern, but I want to go further.

Im looking for stock DRZ or XR 400 noise levels.

" if they cant here me, they cant report me"

Any help greatly appreciated!,!,!
