Hi, i have read here on RCU people putting the Tower .46 sized muffler on OS50SX's. Should i do it, because i have a tower 46 engine sitting upstairs that is on a Magic[:'(] which was junk, and would i get more power with that muffler over stock muffler? Also, would I get enough back pressure? Thanks!!

Yes the Tower muffler works great on the 50 SX. I've changed two over to the Tower muffler.

The muffler points back at a straighter angle and may hit your fuselage?

Enjoy,

Jim
