its quiet at 85 decibel, Not recommend for high perfermance machine, Get alot of blow back. Car is a lot faster with just spark aerator, at idol 88 decibels

Helped some but definitely not a huge difference. Very easy install

Easy to install. Not sure it made it any quieter.

Major back pressure. I installed this in my 3" treal exhaust on my turbo r. And it created massive amounts of back pressure. Before my machine under WOT would run 8600 ~ rpm. With the arrestor I could barely break 7200 rpm under WOT. I think the deminsions are great but the holes are to small. I am going to try and modify it and open some of the hole up like slots. It did definitely become quieter but it was too much back pressure.

Great fit works amazing

They are great i changed to a aftermarket muffler and ended up being way to loud these made it perfect

easy install

You all know you’re not sure what sound your going to get when you buy a new exhaust system. When you bolt on a new RPM sport you’re going to be pleasantly surprised. 2024 Polaris Pro R 4 ultimate

Fit great

Awesome! Love the sound and everything about it

Exhaust level was getting old. It took some of the noise out and for the price you can’t complain.

Sounds great! Doesn't effect sound much, if any. Still crazy loud. The Sport
