Default MVVS 30 muffler

Hi,
I am consider to buy the MVVS-30 for my Zen-120, now since i want to keep the weight below 5Kg i thought
to use the 3270 compact muffler instead of the tune pipe.
from what i have seen the whole tune pipe is heavier by ~ 200 gr then the 3270

what RPM i should excpect to get with 16X12 apc prop ?

also is there wrap around muffler for it ?

Thanks

Default RE: MVVS 30 muffler

Expect about 8000 rpm. The 3270 robs quite a bit of power. (My test engine with Xoar 18x8 prop and 3268 pipe runs at about 8200 rpm and takes a 14lbs plane into unlimited vertical.)
MVVS does not make a wrap-around for the 30. Bisson makes custom 26cc mufflers. (same engine dimensions as the 30)
