anything besides those silencers will do, although i had a pair back in 09, my overall experience with them was that they handled poorly, were built poorly, and were litterally the crappiest skis i ever rode, within 2 weeks of buying them i had delamination problems in more then one spot. Pick up some K2 recoils off evo theyr on sale and theyr fuckin bombproof you will not be disappointed
sry bout the spelling im on my phone
