Noisekiller have updated the kit for the Mini with new improved materials. The transformation was remarkable. It made the whole car feel different even the doors shut with a much more satisfying clunk and reverberation throughout the body has been significantly reduced. The bonnet lid and boot feel much more solid and the carpets feel more luxurious.
Now that the Voyager is equipped with a Noisekiller kit I can hold a conversation without shouting the entire time. The kit makes sure the engine noise does not enter the cab by soundproofing those areas that create those annoying vibrations rattles and roars.
When I first started the engine after installation, I realised what a difference the kit made in muffling the sound from the engine: its clatter was dulled quite dramatically. The mats really do perform extremely well as they have entirely eradicated the noise from below. My music plays sweetly, with our conversations quiet yet audible. I was very impressed with this well-made kit, which I think should be installed by the manufacturer of every Motorcaravan. What a difference that would make.
The transformation once all of the kit had been fitted was quite remarkable. Noise levels and vibrations are down and the car feels much more substantial and you can really hear the stereo and have a conversation at 70mph with someone in the back seats.
When I first started the engine there was little discernible difference in the sound level and, as I drove away I could still hear the same noises though significantly muted. It was when I lowered the door window that the difference first struck me. Normally the Discovery is very noisy in town when the windows are wound down - now, it was quiet. It was a different car.
As I drove towards the Motorway through several sets of traffic lights up and down the gears, I could tell just how much more subdued the transmission noises were: some were eliminated altogether.
The real benefit on the motorway came on those long climbs that demand prolonged full throttle to keep the speed up. Under these conditions of full engine load an old Discovery can develop a level of noise and vibration that becomes tiring. Well not mine any more.
