Pro R Exhaust Showdown! Comparing ALL The RPM Pro R Mufflers!

[@Joblessparadise]

Is there any dyno numbers on any of these ? Some other exhaust options are boasting HP numbers of around 6-10hp

[@RPMPowersports]

Those are unrealistic claims by those people with no data to back it. Our header ( which is proven over and over to perform the best ) with a 3" muffler of ours ( take your pick ) is good for about 12-15 HP on a stock machine. Pair that wit a tune and you'll see even better gains. Hit the search bar and peek around. Dyno shops have done these tests, unbiased, no incentives, and no "deals" from us on products. Our header simply puts the power down. The muffler itself is restrictive, but not as bad as some performance UTV's. Keep in mind the Pro R is in a class of its own being NA. It doesnt reap the benefits of a free flowing muffler like the turbo cars do.

@@RPMPowersportsi appreciate the thorough reply. I have your 3 inch sport muffler on order either the blue tip ( honestly sounded better than the race one on your video ). I will order your header probably next and then figure out what I want to do tune wise . I’m considering bikemans stage 3 for 300hp NA power . I do mostly trail or track versus drag or dune where a turbo setup is more important.

I need atock exhaust dB reading while 1/4 throttle 1/2 throttle while parked. Oregon dB testing

[@RPMPowersports]

The only one that will pass would be the chambered.

[@seanmuehlhauser9612]

​@@RPMPowersports is stock louder than the chambered?

[@RPMPowersports]

@@seanmuehlhauser9612, no, our chambered is slightly louder than stock. It’s 3”, and catless so naturally will be slightly louder which is the trade off for cooler running and better performance.

[@theenduroshop]

is the sport muffler with the quiet core installed about the same db's as the chambered larger muffler?

[@RPMPowersports]

No, the chambered is still quiet a bit quieter.

[@CavidzMedia]

The race exhaust looks slower on take off and fly-by is it because the tires are spinning more? Can someone from RPM confirm which exhaust has better over pull ? Race or Sport?

[@RPMPowersports]

Really about the same, Just a difference in noise and how loud you like them.

[@Joblessparadise]

@@RPMPowersportsany idea how much gain there is from the sport or race exhaust ?

[@RPMPowersports]

Negligible difference, all about sound choice between the two. HP wise from stock you're looking at a 3ish HP gain on a stock header. More if there is underlying supporting mods. @@Joblessparadise

@@RPMPowersports Thanks again for this reply too. I will try to post some good videos when I have the sport exhaust installed from you guys and rip it good n make ya proud haha.
