I was riding my ATV along with some other friends and noticed that one machine was by far quieter than the others, it had a Benz Silent Rider. I knew right then I had to have one, I LOVE IT

Needed to much changing exhaust to fit. Brackets not even close to working. Much smaller muffler than the original.

Put this on my '09 Yamaha Grizzly 350. It is definitely quieter now; I'd say about 30% quieter. You'll notice the sound reduction most when you're at least 20 yards from the running ATV. It sounds a lot further away than it is. Great for hunters. Caveat: this silencer does NOT work with a rear drop basket (at least not on my ATV) because it projects a few inches too far to the rear. Overall, I like it, although this product is pretty pricey for a 1/3 sound reduction. It's up to the buyer as to whether the expense is worth it.

does not make any difference in noise not worth the money

Excellent product, fast shipment, and arrived as advertised. The product definitely quiets my 2008 450 Grizzly engine noise. Highly recommend it.

Purchased for a '08 500 Sportsman. Save your money. May quiet other ATV's but not worth it on Polaris. Most all noise you hear is engine not exhaust. Objectively, I would say you may experience 20% reduction in total noise. That is my opinion.
