2022 Hisun 750 EPS Overall very loud while driving

Definitely seems to have quieted the exhaust noise, if not so effective in the cab itself. Be interesting to see what you get with the sound deadening.

Ok I did finally manage to get some sound deadening installed in my 750. The product I used is a 200-mil peel-and-stick asphaltic/closed cell foam composite from Siless (available on Amazon). I installed it on the panel directly behind your hips (between the seat base and seat back) on the engine side; on the panel behind your legs between the floor and seat base inside the cab; and on the three access panel covers under the seat. I didn’t really feel like disassembling the cab to install the material on the engine side of the panel behind your legs, and I will likely make an aluminum cover panel over it in the cab to protect it from getting damaged, but it worked fine installing on the inside.

I have not had a chance to check dB levels yet, but I would say overall the cab levels have been reduced again by a similar reduction realized with the silencer. So I’m pleased with the results and the UTV is much more pleasant to drive.
