V comp mass loaded vinyl vanagon

Covered the front wheel wells and arches in a vanagon. Used some ultimate and complete coverage with mass loaded vinyl, Huge drop in road noise.

Very good product


Great product

I did up the cab of my 89 Toyota and it went from a tin can to a modern sounding vehicle. Will buy again for future projects.

Van engine cover

I have a 1996 Ford E-350 with the 7.3 Powerstroke Diesel that is LOUD. The engine noise cuts right through the engine cover (doghouse) and right into the cab. It’s so bad that when I’m accelerating to get on the highway or even just cruising highway speed that it’s difficult to think, let alone carry on a conversation. It’s bad enough that if I’m alone in the cab I usually put in ear plugs.

As a first step of deadening the sound I reached out to the B-Quiet team with a few questions and they gave me some good pointers. From there I purchased the B-Quiet Ultimate and the HLiner. I removed the original cheap insulation and installed 2 layers of the Ultimate (probably only needed 1, but it I don’t regret adding a second) and then the HLiner. The before and after comparison is drastic and I can finally drive around with the family.

To say that I’m happy is an understatement. I will absolutely be buying more from B-Quiet when I sound deaden my floors, doors, and wheel wells.

helpful not awesome

I used the side x side sound deadening package on my KRX 1000. The package dead help considerably. The engine sound went from ear piercing to communicating with passenger with a raised voice .
A better installation instruction would have been helpful with installation tips. I had to come up with my own attachment method for the vinyl backed sound deadening materials. The method worked very well. When asked the company for tip on installing the vinyl backed material they did not respond.
The vinyl backed material is brittle and tears easily. They sent barely enough sound deadening product for engine side of firewall. Would have been nice to have additional sound deadening material for use under the seats on the engine side of firewall. Reality is additional sound deadening would not be much more effective as the sound is coming around the firewall through rear windshield and in through side window areas.
The sound deadening material used on engine side of firewall is not adhering as well as I had hoped even after cleaning with acetone.
Overall I am satisfied with the products and sound deadening function of the system.
I would not consider this a kit specific to a machine. I would consider it a couple of products grouped and sold together.
