How are the vents and the noise level at highway speeds?

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.

Is not a silent helmet, I mean the level of noise and vent is annoying at highway speeds

Don't have a lot of experience to compare to, but my best evaluation is average. I have a bluetooth sound system that I put in it and I can comfortably listen to music without having to blow my ear drums. With the Senna sound system talking on the phone is clearer than when I'm parked and talking on the handset. The helmet is a very good buy but I'll probably upgrade when I can.

The helmet is moderately quiet. .considering..I like to know whats around me....it quite quiet. ..You..are able to hear yourself think. If that helps....and the vents are functional.

The answer would require special measurement equipment (that I don't have), but will also greatly depend on the intake and exhaust ducts and whether all these are covered with a sound insulation. Probably the manufacturer has some data determined in "standard" conditions.

At low-medium it's almost silent. High is not too disruptive, turbo is loud enough it will interfere a bit.

Whether from being well constructed, or just new, these sliders seem to latch fairly securely, and seal reasonably well. Although the Wrangler is not without its customary cabin noise anyways, I don't find that the sliders let in much extra air or noise when I'm travelling at highway speeds. My old sliders blew out easily too, as you described, perhaps it was a blessing in disguise that they were stolen.

The low & medium speeds are adequate for white noise. That's what I use it for.

It's definitely louder than stock, but it's not outrageous. It has a great secondary report, especially if you have a standard transmission. I love mine :)

This is a quiet muffler. Not much throat to it. But seems to flow good. I have it on a 4.3 vortec. It is small and have only have on it 1000 miles or so.

The sound is great low tone at idle and little to no noise when on the highway but it is very aggressive when passing and accelerating. Also looks great on the Mustang.

They're still pretty noticeable, not like jet engine but still fairly audible depending on how close you are to it. I sit fairly close to it and can hear it, its not obtrusive and if you have it far away you wouldn't notice it. I would try for quieter If it'll be close by you and Noctua's are always nice, but it you have it far away I wouldn't bother.

The owner's manual states that the noise rating is 58.5 db at the highest speed (turbo). It's much lower in "normal" mode.

There are three speeds, and at F1, the noise is minimal, and shouldn't disturb sleep. The second, and high speed anr not intrusive, but somewhat louder.

I use mine in a Semitruck, it's loud enough to get over the engine, wind & road noise.

They get pretty noisy at anything above 55 mph. Only recommendation would to not overfill them. They were tolerable up until I had them rotated and the shop overfilled them past the max psi.

When I installed mine, there was terrible wind flapping noise at highway speed. In order to fix this, I had to cut off the rubber flap at the front of the bed cover (near the back window). Since I have done that, it is perfect.

I haven't had that problem. I have been up to 70 mph on the freeway and no trouble. The noise from a soft top at that speed would cover up any noise, but the seal seems good anyway.

they are fairly loud. they drown out a lot of the engine noise on my 62 falcon if i'm standing next to it while running. i have 2 installed, louder than an average electric fan. i also have mine mounted in front as pusher fans, that may make a big difference

Hi, I own a 2013 dodge ram HEMI, Yes there is definitely a bit of an annoying tone when at cruising speed on the freeway, I will actually click the button on the gear shift lever and downshift one gear to increase the RPMs just a bit and that annoying tone goes away, I love the muffler and around town it sounds really great, I like that the truck sits idling nice and quiet But when you get on the gas it sounds Excellent. I Wish it didn't have the annoying tone (not an issue in town) but you get used to it, I'm pretty sure I would buy it again. P.S. If you like driving a little faster on the freeways let's say 75 or 80 there is no weird drone noise. Increased rpm's Same as downshifting at 60 miles an hour. Hope this helps a little bit.
