RE: RCMK rear exhaust
It's almost the same as modding a side exhaust engine with consideration that the top-end is 90 degrees off.

RE: RCMK rear exhaust
I have a stock K30 rear exhaust also...trying to get the best out of it. No mods yet, however it seems to have enough grunt to get to a competitive level. I think with the right prop it can be cometitive in heat racing.
What type hull are you using?

the older RZ sufffered piston problems
I run the the K30 rz topkit with only a couple of mods but left the sleeve alone and piston still looks good and plenty of power
