Massimo 400 - Noise reduction

Recommended Posts

I recently purchased a 2020 Massimo 400 EFI and  began installing soundproofing to lower the overall body noise.  The model I choose is the crew cab with rear facing seat and diamond plate bed.  

the first phase involved removing the rear deck and applying Noico 80 mil sound deadening mat over the exposed diamond plate sections of the underside.  This immediately removed the  sound of vibrating metal plate!

Next phase is to continue this application to the interior of the plastic  around the engine compartment and then any other plastic panel that has a "hollow" sound.   It will add 2-3 pounds to the overall vehicle weight  but it makes a huge difference in noise reduction.  One question I have - there is a vent directly in front of the engine (behind a drivers leg about calf level)  I am strongly thinking about covering this as the level of engine noise here is huge.  The engine is water cooled so I don't think this is a problem as the air input is minimal - but i don't wish to overheat the engine.

Thoughts?

      I need help locating a rear cv style driveline for my early 2008 t4 trooper. I have broken 2 ujoints now and almost put a hole in the oil pan! I found one place but they wont return my calls. The mud season started and i got a big paper weight. Any help is greatly appreciated by me and my family.

      I purchased a Red Massimo Buck 400EFI recently from Massimo Motor.  It was very simple to purchase on line, it was quick and painless.  After placing my order, I got a call from the Massimo Motor Customer Service Department (Eddie).  He wanted to confirm my order and he let me know that they were building my UTV and gave me an estimated date of completing and delivery.  Upon completion of the unit, Eddie reached out to me to let me know that it would be shipping and that I should expect it within 7 business days of his call.  I actually received it 3 business days after his call.  The truck driver was very polite and helpful.  We got the UTV off the truck and away I went.  We have a small tree farm and we needed something that we could use to maintain our little farm with ease.  The Buck 400EFI performs as expected.  It runs really well; it looks good and the most important thing about it is that my wife loves it.
       
      A few days after receiving my UTV, Eddie from Massimo Customer Service called to make sure that we had received the UTV with no problems and to see if everything was OK with the unit.  He told me that if anything were to come up with the unit, to not hesitate to contact him and he would help us resolve any issue that may arise.
       
      I am very happy that I purchased this UTV from Massimo Motor and IF I had to do this again, I WOULD in a heartbeat.  Eddie at customer service is outstanding and because of him, I would recommend anyone who is interested in purchasing one of these UTV’s, to ask for him.  He will take good care of you.
       
      Sincerely
      P.Q.
      Very Happy Customer

      So i have a 2018 Hisun Sector 750 Crew and while driving the noise level is outrageous.  I want to find a way to decrease the decibel level, so does anyone have any ideas!!! i was thinking about installing foam on the roof enclosure and possibly putting something around the engine bay area.  I have not found any companies that makes a suppressor for the muffler...Any help would be appreciated.  thank you

      Hi, I just purchased a Massimo MU500 that we are going to use in the North Georgia mountains.
       
      After the first couple of test drives it seems a) somewhat underpowered and loud as hell.
       
      So wondering if I switched out the mud tires with something with smaller tread if that would maybe help?
       
      Also I found a muffler replacement called the “silent rider atv silencer” and wonder if that would help with the noise without killing power.
       
      Thanks!

      Hey everyone,
      I have made some modifications since I purchased my Massimo 500 MSU/UTV earlier this year and I thought I would share with you.
      Please give me some feed-back and let me know what you think of my MODS.
