Hmf ?

Will any other Spark Arrestors work in a HMF pipe ?

my guess would be yeah, as long as you can fasten it to the body of the muffler. all the spark arrestor is, is a screen which catches and suppresses any sparks that may occur. but it must have an approval stamp on it.

a yoshimura quiet core or spark arrester will owrk, they have the sme size holes. i think lrd might be the same also. not sure about others those are the only ones i had experience with\
