quieter RZR Muffler - Polaris RZR Forum

I sent a thread in on getting my RZR quieter... and I found something that helps. I went to an auto parts store and picked up a stainless steel universal resonator... slid it on, tightened up the 3 bolts and it did take the edge off the constant roar. Cost $23.00 and doesn't look bad at all.

Looks good

great fix, how much less sound do you estimate

That sounds like a good way to go if it quiets it enough. I too like more quiet, noise tends to wear me down if I have to hear it all day. I don't understand why anyone would pay money to make one louder. What parts store did you find it at?

The resonator on the end of the exaust doesn't quiet it much, maybe 10% on the highway, (It helps some) but there is an resonator that screws onto the tailpipe that has a baffle that would work much better.

This one has some glass packing... but no baffle. I also talked to one muffler guy who said to put a bend down and add a resonator. (Still not quiet)

There are also smallglass-pack mufflers that will quiet it down much more.

I Emailed Polaris, they just blew me off, told me to call my dealer who is useless. Thanks Polaris.

I recomend the Benz Silent Rider. I Installed one, and I like it very much. I'd say its 50% quieter, slight loss of power, easy to install or remove.

Thanks Jom, I did add on a small glass pack that I slide on the end of the muffler tip, and rad a bolt through to hold it on and it did help. Still a little loud, but much better.
I wish Polaris would comment on what kind of back pressure would be allowed... then it would make it east. (Don't want to mess up a motot for quieter huh?)

I would be willing to sacrifice a little power to get quiet. The noise ruins an otherwise awsome ride.

you def don't want a set of looney tuned then
Aturbo cuts the noise very much Im guessing about 1/2

arzeear- I also would not mind losing a little power to get our RZR quiet. I wonder if anyone will make just a muffler to replace the stock one, ever???

I guess we can only hope someone comes along and finishes the exhaust system where Polaris left off. I also hope Polaris reads these forums and realizes not everyone likes noisy exhaust.

has any tried to hold a car muffler up to the stock pipe to see the difference. I would but I have lte duals.

i put a pair of stock 07 yamaha r1 mufflers on they are a baffled muffler and are very quiet.. they will also add to performance as they are designed to flow with a 1000cc 10,000 rpm motor. i'm doing a new head pipe for them now, but the last time i had them on i was playing with a stock rzr, he was behind me and i could hear his exhaust over mine..
470ltz drove mine down a straight away, wide open, when he went by me he was still about 50 yds from me and i could hear the belt and the clutch and the stereo, over the exhaust..

i've had the two brothers on for a while and i'm re-doing the yammie crossbreed exhaust. i'm looking forward to the quiet exhaust again
