Guys,

I'm about to upgrade the engine in my 38" SD3 to a CMB .45RS and I would like to know what pipe, header, prop and pipe length you recommend?

Thanks,

James

my father runs a x440 x 3 blade stock pitch or slightly depitched on his with a rs

the new cmb 45 nitro pipe with a muffler works well.. very well in fact.

might get ahold of my father steve wood for a price on the pipe.. he sells cmb motors and parts.

WOW! I just tried the x646/3 on my D-mono with a CMB 45HR and she REALLY rips now. I switched from a x450/3 and while I lost some cornering speed the straights are ridiculous with the x646.

The CMB nitro or AB#2 same pipe run real good on the RS. At 9 1/2 you will get all the RPM's you will need.

The X450/3 no mod's just S&B is a very good prop for heat racing hard to beat.

Don't cut the pipe put it right on the eng no header with a muffler.
