Almost makes it too quiet and takes the fun out of it with my KLR 650.  But if that's the case, you can always drill it out a tad bigger in the end.

While there are other more pricey versions of the CycleOps, I find this great.  I don't find the bike that loud.  We do have the Training Mat and it is on carpet, so I'm sure that helps.  But if you have it on carpet, I would not go for a more expensive version.  I can watch TV in the same room as someone using the machine.  In reading other online information, I had a much greater fear of the noise than what actually occurred.

It's almost too much low end, sounds funky when you have it turned down low but rocks when you crank it up

I have an 07 R56 Cooper S with 68,000 miles. Around 63,000 miles or so I began feeling slop between shifts. I long suspected it was the motor mount. I had tried a few other things, but then finally replaced the stock motor mount with this. I figured it was the street edition, and I always did think the mounts were a little soft between shifts. So I replaced this, it wasn't so bad, although my motor needed to shift a good half inch for this to fit, since the old mount seems to have been a bit bent.

After installing this it was like night and day. The slop between the shifts disappeared and the shifts were brisk and sharp. But unfortunately the rattle produced by the motor at 2,500-3,200 RPM is pretty loud. At about 2,900 RPM it is pretty much impossible to have any sort of conversation in the car or hear the radio. It is partly due to the plastic interior of the MINI being a bit rattly, but really the vibrations are too much. If you put that aside completely, the car drives fantastic now. I love it when I'm driving by myself, but I have to drive really carefully if I have any passengers.

I thought the street should have been a bit softer, since there is still the race... It does what it's supposed to do though so I can't give it a bad rating.

PS. Let me know if anybody thinks my particular case is unique and I have something out of whack.

Installed it on my 2007 Triumph Bonneville. Took two tries to figure out it doesn't fit beneath the rectifier with a rectifier relocation bracket. The clearance between the horn and the front tire isn't enough; when braking the tire rubs against the horn. Instead I installed it on the right of the rectifier with the bracket that comes with it. It's a bit bulky but it's loud, so it's worth having if you use your motorcycle on a day to day basis. Hope they make a reversible bracket in the future so you can install it either to the right or left.

I like that it has the bubbling and vibration options except that it is soooooooo loud.  I have to turn anything I'm listening to super loud just so I can barely hear it over.

It's very loud.  I've had some dogs chase me on my bicycle and WHY I bought it.  It's much better than a spray that can MISS its' target.  IMO they could redesign the holster.  It's very cheap and flimsy.  The only way to use it is to wear a belt and clip it to the belt while on your cycle. This makes it annoying though because it's one more piece of gear you have to put on.  They could come up with some attachment to place on your handlebar and then you could grab the horn quickly to use it!  When activating the horn though you must use it UPRIGHT.  It won't work if the horn tips to its' side.  When I lived in this small town of 15K I showed it to my mail-carrier and he mentioned it to his boss and his boss ordered the "dog horn" for ALL the carriers in the town against unleashed dogs.  It was easier for homeowners to let their dogs run loose than to by a gun.  The cops didn't care.

It works (spins I mean), but it is too loud that I cant bear it. So I had them returned.

Has a bassy note to it which sounds nice but I don't like that it drones a bit around 1600 - 2000 rpm. That's the rpm the engine is in when driving in city traffic. Exhaust will be removed again.

There amazing and great audio but the guides for it to clip on to the harness brakes easily but I love how easy it is installing in your helmet. I use mine with my cusion and go off roading with atv and dirt bikes just wish it could be louder though. Did I have an atv raptor 660r and I can barely hear what any one says.

It works as specified; i found it to be a little bit to noisy for what i intended to use.

Very good ventilation but not comfortable at all especially if your bike has no suspension.

It works, but it's VERY squeaky and adds a lot of sound to the mic from nearby vibrations. You have to be very careful not to bump it or get too close with anything with a heavy low range, because the metal springs on here often show up in recordings.

I think I have figured out why there are a mix of opinions about the noise level. My guess is that there is a quality issue and some people get better working parts then others. Mine CAN actually be very quiet but it is short live, because most of the time it sounds like a loud buzzing, rubbing, or rattle. I tried to shave the fins on the part that spins with a razor thinking they may be rubbing against the sides, no luck. I've pulled out the tube and put it back in countless times. I pushed it down hard, pulled it out some, but there is no sweet spot on mine. I will add a video soon to show how noisy it runs. It also came shipped with a nice crack in the top cover right out of the box. I already trashed the box and shaved the fins with a razor, but I still may try to return it. This is way too loud. The filter does do a great job, but quiet it is not.

EDIT (MOD FIX):
OK, I figured out why this is so loud. The part that goes into the motor (fins attached to a magnet) is two connected pieces. However, this makes the spinning part with fans vibrate against the magnetic piece below it. So, I dried it and took a small piece of scotch tape and tightly wrapped it around the top of the magnet and the bottom of the fin. This made it act as one solid piece. I put it back in the motor and it is now super quiet. Problem solved for next to nothing.

These pipes were installed on my bike when I bought it.  Sounds great, much better than a stock bike.  I recently had the exhaust off (installing forward controls), and I noticed the screw to remove the baffles.  Oh yeah, definitely turns heads.  I've actually had people ask me what kind of Harley it is.  Obviously they can't see the giant "Honda Shadow" on the tank lol.

The noise reduction was not as good as I had expected. It is well put together and easy to adjust. Better for someone who does not shoot much

Installed these puppies in my ESP M-2 which comes stock with an Original Floyd Rose. Spring tension is slightly less than the stock springs I had inside - not a big deal though as this is easily adjustable. Although the springs themselves are noiseless, they still carry vibrations to the claw plate, which still resonates during fast stops. Had to end up putting tape on the springs to eliminate all noise, so in the end the "noiseless" gimmick is kind of useless. The springs are black though, which is pretty metal.
