Re: Quieting down a gas cart
I had an older G14 Yamaha it was always loud. Rebuilt the motor and it ran like a champ, but it was still noisy. It was more in the valvetrain than the exhaust. Can't speak to the newer ones, but wonder if it is similar.
I would try some heat shield/soundproofing unless you are sure it is exhaust sound.
Good luck!
