Massimo MSU 500 Extremely Loud

[rtate1050]

Hi to all . My name is  Rich . I've recently purchased a MSU 500  from Massimo in Texas .  So far I'm impressed with the overall quality of the machine . My only real issue so far is that this thing is extremely loud . You can't even carry on a conversation with a passenger without yelling which is annoying. My first plan is to add some Dynamat to the underside of the engine cover and the seats.  I would appreciate it if anyone has this problem and any solutions . Is there anything in the aftermarket for the exhaust system ?

Other than that I'm pretty happy with it so far.

check the exhaust pipe right out of the head.. Prone to cracking  and breaking off . ANOTHER factory defect from Massimo Poor Quality .. I implore you to bypass the fan switch and run it 100%  when key is on .. MSUs have massive overheating issues that   blow head gaskets and warp or crack heads.. And Massimo WILL NOT WARRANTY IT

I read that on another post and I checked it and it seems to be OK. Thanks for the input.

It doesn't seem to be as loud standing at the back with the engine reving. I think that sound deadening in the interior will help a lot , but we'll see .

There is already a little insulation material on the underside of the engine cover.  If you add more I'd like to hear if it helps.

Good to know that there is some already there . 

I ran into another problem  though. I went to pull the seats and console to check the insulation and check the oil and cannot CANNOT get the drivers seat to come out. No matter how hard I pull on the lever it will not release ! There has to be something wrong underneath with the release . The only way that I can see to get to it is to remove the panel in front of the seat and hopefully get to the latch from there.  Can't really do anything until I solve that problem. 

Anyone have any suggestions ??  I've tried spraying lube underneath but no help.

I don't have the stock/original seats or seat bases in mine.  I do recall one side being harder to get out than the other but I was always able to get them out.  Sorry, that I cannot help you on that one...

Yesterday I was determined to get that seat out. After a lot of rocking and shaking , it finally came free . Turns out that the bolt that the seat locks onto was slightly bent.

After careful and precise application (a couple of hard whacks ) of a finely calibrated adjustment tool ( ball peen hammer) the offending part moved into alignment. 

Problem sorted....
