is mnr web site down? tried to enter but i had no luck. does anyone know the diamiter of mnr exhaust on outlet of 4-1 primarys? will a 2" diamiter silencer slip straight on or are they slightly larger like the 2 1/2" mk silencer?

Mine was 2"

thanks lee. are the cec headers which mnr do the same diamiter as their bec ones?

I have no idea sorry Daniel

Just checked a link pipe I have which was used & the outlet on the headers was 2" internal diameter.

oops forgotten to renew the web hosting just trying to do it online now
primaries are either 1 1/4 or 1 1/2 after collector 2 inch, 2 1/2 inch , or 3 inch

cheers
