Thanks for the reply. I checked with Dynoport and they dont seem to make anything for Arctic Cat. Alot of differnet sites have silencers for the the 1996 ZR 580. So what im wondering is if both engines are similar, with just the suspension being different from the two, if the silencer for the ZR 580 would work the the EXT 580. Both being the same years.
thanks!
