the normal exaust is fine,
and yeah the restriction is in the valve,

alot of people can derestrict by changing the reed valves from metal to plastic with metal stops,,
bare in mind its been over a year since i last laughed at a two stroke

My old KMX had restriction in the KIPS and the exhaust (a cone in the expansion chamber entrance), it was purchased as the full power version but had to be run in with the restrictors in place for some reason.

But that was when they first came out many many many years ago.
