YS FZ140.DZ140/DZ160/DZ170/DZ175 Muffler Set.

This muffler set can be used on the 1.60 & 1.70 as well for sports use, but the sound will not be as good as an Hatori system.

Tip. Some customers who did not tighten up the muffler correctly have had the muffler come loose or fall off all together. It may be advisable to have a short length of pull-pull cable attached to the silencer & fuselage so the silencer will not be lost if it comes off!!!!
