I don't know if there are any better out there but I went with the BENZ Silent Rider on my ZForce 800 only because of reviews and other people's recommendations. I've been happy with it for several years now. There won't be one specifically made for yours so some adapting will be necessary..which will probably be the case with any others as well. I bought one for a larger engine size then I had so there would be no restriction, just noise reduction. It did mean I had to build a new exhaust end with a different angle but go from about 1.5" to 2". There's a write-up on both stages in the How-To section.
