One of the older guys in our club gave me (

) a YS .45 side exhaust...
He's in his 70's now, and I got him hooked on electrics, and he's gettin' rid of some of his glow stuff...he also gave me a Magnum 1.20 4 stroke w/ very little time on it!
Anyway...
I'm thinking of replacing the tired Webra .50 /Ultrathrust in my WM Dago Red w/ the YS.45 and a pipe.
I have a header, but I want to know which Macs pipe would be the best for max R.P.M. and what prop (one of them meat slicer APC's

) and plug?
This is my first YS so I ain't too sure yet what to go with as far as prop/ plug, etc. ya know?W
It oughta be faster than the Webra with the Ultrathrust, shouldn't it?
