what is the noise level while driving on freeways at high speeds?

0... Zilch... Nada... This thing is very aerodynamic, feels like nothing's there...I made a mistake of putting on a harness on it the first time I used it, to make sure it's secure, the strap made so much noise suring driving I had to remove it after the first 5 minutes... This product is worth it!

Had very little noise - if any - from the cargo box. What little noise heard was probably from my cross bars - and that was at highway/interstate speed. Cross bars with cargo (with load) affected mpg by about 5-10%.

Gee, I must have gotten the bad one. At 40 mph or higher it sounded like a loud bee hive up there. The front top lip would vibrate causing the noise -- I could see it though the sun roof). While I tried a strap on it (I don't know why) the strap then made the noise. I've ordered a more expensive and different brand which I will review (good or bad) sometime after June 8, 2015.

Hi James, I found the noise level to be negligible. You'd hear more noise from a bad road surface. I have to admit that I wasn't listening for it and didn't hear any.

I expect a little noise from fans, and while this one is louder than most at HI, I think the LO and MED speeds are reasonably quiet. But the sheer force of air blown on HI from such a little fan makes the extra noise worth it.

I have a Victory Judge with aftermarket exhaust which is substantially louder than stock. At highway speed, no one I talk to can tell I am on the highway. As for the speakers, they are more tuned for voice than music (I.e not too much bass) but I still like em a lot and can hear my music at 70+ mph.

Not really more than stock noise no. If you got an intake or something I'm sure it would be more audible. I bought it to hold my high boost levels though not for the noise.

The vents are average. The noise level is kind of high but it has a chin cover built in which helps a lot too with wind and noise. Sometimes when your around 60+ mph and turn your head it whistles but its only if you turn your head to a certain angel.

I measured 86 dB right below my fan on high. Belt drive is supposed to be quieter. Higher quality is quieter too, but much more expensive.

Hi Glenn, I cannot answer that with any certainty as there were 2 Mhz levels. The best way to find out is from one of the spare parts resellers like Greenbriar Dodge.

Not that loud interior noise, still is a drone over 55 mph though. Had a Flowmaster 10 on before this on and was twice as loud. Super 40 seems just right

The fan does produce enough ambient noise if you are nearby it. It increases a little bit with each speed.

8.5. Its very loud on my honda accord vtec. Maybe depending on what car u have. Deep sound on low rpms. I threw back on the silencer because I I was making alarms go off where I live.

Not sure. It is plenty loud for us and I think there is a volume control but we have a quieter engine and full face helmets

It's twice as loud. Makes u want to drive more aggressively just cause it sounds so good.

I have not had any problems at freeway speeds 70MPH+. Unless you drive maybe 90MPH+ you should not have any problems.I was initially wondered if they would put the wheels out of balance because they are a little large but at 70MPH I did not notice any additional vibration. If you plan on some very high speeds you should get a wheel balance with the sensors installed.

Yes- with windshield you can hear it clearly at 60 mph!! You only have 3-4 hrs of play time, & you have to turn off the unit by unplugging it! For optimum clarity, aim speakers towards you!

The unit is rather loud on F4(highest speed), much quieter on F3 and almost unnoticeable on F1(lowest speed).

If you have your radio off and dead silence in the vehicle you can hear a slight whistle while cruising at highway speeds. When you get on the gas hard you get a nice v8 throttly sound almost like you have exhaust.

I do have these on my top of case exhaust. They do make noise at a higher rpm (Not a bother.) I control this with a fan controller. When I need them at higher speed, they are turned up. I turn them down and they are quiet. I have had them for 2 years now and they still work well.
