Noise Reduction

Hello. I took my new to me Teryx out, and it's pretty loud. I've researched a bunch of threads here on how to lower the decibels in the cab. I do have a top and a windshield, and I know that contributes.

I've purchased the secondary Kolpin exhaust, so that should lower the sound for those behind me/outside the Teryx.

It appears most of the noise is coming from the mid engine/transmission. Has anyone tried the following (successfully/unsuccessfully) to reduce the noise:

1. Lay down 1/4" - 3/8" rubber on the center section/bump inside the cab - not underneath, where the engine/tranny is located (similar to how one might lay down floor mats, but instead over the motor area) to help absorb some of that noise?
2. Has anyone tried using "car undercoating"... that spray stuff, on the bottom of the Teryx

Just got back from a hunting trip, and this thing went everywhere I wanted it to go.. in 2WD. I tried softening the ride a bit, because it's pretty rocky out west, and I noticed a small improvement, but hey, I'm driving over rocks that are 4-10" big.

Just need to get the noise down.

Thanks!

The easiest way to get the noise down in your Teryx is to turn the ignition switch one click to the left.

Seriously though, all Side by Sides's are loud. I've seen many people try to quiet these machines down and almost all of them have had limited results. The amount of effort spent compared to the results achieved isn't worth it in my opinion. But you are right, your windshield and roof definitely make it louder for you. I have both, plus a rear screen and I've just gotten used to it. I suggest ear plugs if its too loud for you.

I too have wanted the noise to go down a bit. Over the winter, I am going to pull apart the center area engine cover and install dynamat all along inside with a 1/2 thick material and then also use some type of rubber as well over top of engine cover. Kawasaki has padding and a small rubber cover now on my S model, so they have cut down a bit compared to older models. But a little more never hurts. Plus it’s something to do here in the winter when’s it s freezing outside.

Ya, I've seen people putting in dynamat underneath/over the engine, but not in the cab itself. I'm looking for rubber sheet that I can try out.

The trouble with noise is that you need to get the area completely sealed, and that is probably why most people have very little luck reducing the noise. You can put all the insulation and sound deadening material on plastic panels you want but the few remaining gaps lets a lot of noise in. Same concept as water proofing. Use a car as an example.....leave a window cracked open 1/2" in a rain storm and your seat is soaking wet. So the fact that 99% of the car interior is water proof doesn't help the fact it has one small open gap to let water in.

I agree to an extent with you. But adding insulation/sound deadening material to all the plastic will help and it’s better than nothing at all.
Plus, I like to tinker with things and prove people wrong.

Yeah. Noise. Drives me nuts on all of them too. If you can make a 1500 motorcycle dead pan silent, why can't a 4 wheeler be quiet too?

What does work? Noise canceling head phones with bluetooth for audio. Bonus if it's got a com link too so you can talk. Now you got tunes without cranking the stereo to hear it (if you can even hear it), and communication.

Rugged Radio? $1200. Same with aviation gear, but that works. Sena Tufftalk for $270 each, unknown on the dust resistance yet. Let you know.

Teryx, lawnmower, Harley, electric golf cart, tractor, stock car. One of these things is not like the other ones... ICE machines make noise.

I might be out to lunch but doesn't a lot of the noise come from the air intake and isn't it up under the rh side of the dash?Seems like anything over 1/3 throttle(I haven't used mine in a while so maybe I'm off) and it screams, like flipping the air cleaner lid on an old chev v8 but way louder.

Our bikes also vibrate ALOT. A low hanging fruit that can be picked is to ensure the rubber snubbers are doing it's job and keeping the door snugged up against the latches. Its a quick fix and for me, doing this cut down on some of the noise. I also cut some sturdy rubber/foam to slide between the bottom of my seat frames. It covered up the holes under the front seat and reduced dust, heat (and blocked some noise). I haven't put much effort in noise reduction, but these 2 things helped some, are quick and easy to do, and can be done with things you probably have laying around your garage.

I have no idea where it comes from, but all I know is that I can hear what sounds like the transmission... and/or motor. Noisy as heck.

I wish I could hear the rattles... it's the somewhat hi-pitched motor/tran combo in the middle, I think. I'm going to start plugging holes, etc. until I can narrow it down over time.
