How loud isthe rumble say compared to monster ovals?

It is pretty reasonable. Unless you actually get on the gas they are pretty quiet. No baffling material inside, but there is a back-pressure piece. Love them, did not have the fuel injection reprogrammed and the bike runs great. Get lots of complements of the looks. Happy with them. Good Luck!

The idle is a little quieter, maybe 10%, or so, but when you're on the throttle there is no ignoring your presence.

Don't know "Monster Ovals" -- Tri-ovals make themselves known when you crack the throttle but are relatively quiet during cruise and idle. NOTE: My ECM was re-mapped by the Victory mechanic using their Digital Wrench software -w- link to Polaris.

friend has monster ovals and his opinion my tri ovals are a little louder than his. monsters have a much deeper sound which I like, but price is way to high...happy with the tri ovals hope that helps

Since the monsters are larger the Cobra's may not be as loud. You can talk over them at idle but they have a nice bark when you get on the throttle. I'm really happy with mine.

I am not a race fan, but seems to me that Nascar is already REALLY loud. These will help with hearing quiet background noise. Such as subtile wildlife noises on a quiet night. You may be looking for noise canceling headphones - that is NOT what these do. However the earphones with the electronic in the off position may help muffle the noise to some degree.

These are fine for a truck. They create a very nice rumble. At first they have a bit of a drone sound inside the vehicle, but once the mufflers have been ran for a while the drone starts to quiet down leaving deep rumble. When I installed these on my 91 Mustang GT they sounded great, but if you tend to open it up a lot such as racing light to light, you will find these mufflers can be quite loud then and will mostly attract law enforcement for several blocks around.

These mufflers really are not loud, on a db scale its about 85 at idle and 95 when you really get on it. I say around mid rpm it starts to make sweet music to the ears, nothing to disturbing kinda like a stock G35 IMO, a nice performance note. On some motors you might have a little rasp, but this can be fixed by adding another resonator or a nice tip positing downwards to bounce the sound waves off the ground.

We used a splitter at the Phoenix race. We could each adjust our own volume. Worked great.

Depending on mods it can get pretty loud. My car had good mods and it was very load buy I live in GA and the cops don't really pull us over for stuff like that

The volume is slightly lacking. I used it at the Indianapolis GP and 500 and was able to hear fine when the cars were not there, but I had to have it turned up all the way. When the cars went by you could not hear it. However, I was only using ear buds. A headset with a volume booster may help. I will be going to the Milwaukee Indyfest in August which will put the cars in constant earshot and I will report back how it does in that situation.Update: was OK, but again was only using ear buds. I would definitely recommended noise cancelling or amplified headset.

It's open design, so the motor is right in front of you. I would say it's above 100 db when it's running. Louder than my Bosch 4100 for sure.

I found that "A NASCAR race car is measured to be about 125-130 decibels"....the Hearos earplugs reduce the decibles up to...or down to... 20 decibles, so that would be 105-110 decibles of noisen depending of seating, with the earplugs in. Based on CDC statictics, you could listen to about 91 decibles of noise for about 2 hours, without it starting to impact hearing. So I would recommend buying/using a stronger decible reducing earplug for the NASCAR races... good luck!

I highly recommend Borla. They arent loud and obnoxious like flowmaster can be. On my 01 F150 gives me a nice low rumble getting through the gears but is nice and quiet on the highway... until you stomp on it then let the screaming commence.

probably not much, i can hear car noises when i'm outside perfectly fine with the included foam sleeves if you buy the tri flange ones, those block really really well (but pretty uncomfortable for me), also the yellow foams are garbage, they don't block any sound

Hey Joe.....I would say louder then a regular car vacuum for sure....I use mine with close neighbors and no complaints.....I will say....if you have it on warp 10....i.e both engines I wear earplugs when doing my wheels....its so powerful that it creates a high pitch.....other parts of the car its all good....Ive actually used it on one engine for body of car 2 engines for wheels.....bottom line it REALLY WORKS....but it is loud on both engines.....need anymore info Joe Im glad to help....Im a maniac about how I keep my automobiles and this was a great edition....plus ear plugs....remember even if it is a little noisy...it gets the job done REAL REAL FAST.

I guess it depends on your vehicle roof line, but I'd wager there is a negative impact on mileage. The included faring is supposed to help reduce noise and drag, but I think it adds a lot to the noise, anything over 30-40 mph I can really hear it with my Subaru.

Its about as loud a medium box frame fan. although this varies alot on how you have the exhaust set up.

I'm using 90psi and rally loud. More pressure would probably be even louder.
