I have had both the works and platinum PC pipe on my 300rr. Folded the works pipe up first Enduro race. The platinum is sturdy like a Gnarly. Neither fit as tight as the Gnarly and I ended up using the copper o-ring of a 03 KX250 to stop a little pipe rattle. Also run the FMF o-ring and spring kit. Nicer o-rings. I thing the engine has better over rev with PC pipe and love running shorty silencer in woods races. 4-strokes can hear me coming now.
