Note: Graves RC Coupons are not applicable with this product 

This is the 7/16" Muffler Extension for the
#761 & the #871 mufflers

This Muffler Extension is a 7/16" spacer that installs between the muffler
and the exhaust port on the side of the cylinder head. This results in the
muffler being farther out from the cowl of the plane. One might elect to use
one of the muffler extensions to keep the fuel residue farther out from a
prized paint job or if the aircraft has a large cowl and the muffler isn't far
enough away from the outside of the cowl.

This fits the: .10FP, .10FP-B, .10FP-BX, .10FP-S,
.12CZ-1, .12CZ-2, .12CZ-R, .12CZ-Z,
.15FP, .15FP-S,
