You don't need any special hearing powers to hear it. I heard it immediately, but my wife was the first to speak up about it. "Sounds like a junky old car" were her exact words. It is a very objectionable sound. Sounds like a slipping fan belt. In order to not hear it, you'd have to have a hearing problem. From all the posts on the subject, it is obvious that not all Sprinters are affected in this way with the eliminator. Don't know why. But those complaining have a very legitimate gripe.Thanks for pointing out this difference that some motorhome owners of the 2.7L MB engine may experience with the resonator eliminator instead of the actual MB part. Many RV owners travel with animals, creatures that are much more sensitive to sounds not heard by the human ear. I know that the largest U.S. engine mfg of OTR engines had to redesign their turbo when it was discovered truck driver's animals refused to travel with them because of the unbearable scream coming from their blower. This could well be the reason why the resonator was developed by MB - all engine makers put their product through a comprehensive sound study and, while no person may notice the difference in the sounds with and without the resonator, your pets may have a totally different opinion. Please understand, this comment is not based on knowledge from the maker, just from a conversation with a sound engineer from a competitor engine maker. Take it for what it's worth.
If we weren't already into the less than 20 degree snowy weather here, I'd re-install the eliminator, take my Sprinter for a ride while recording the interior ambient sound with a Sony digital memo recorder, then post the before and after results on YouTube.
