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.
