Sound Proofing Engine Compartment

[Oneiric]

X&X in Ocala will no longer service carts they do not sell. Does anyone retro-fit gas carts adding sound absorbing insulation under the seat and in the engine compartment?

I would be interested in cost of this also. And does it really reduce sound levels of gas engine. I have the 2014 Yamaha with EFI
