Cabin noise

Bonzo

Only way to really tell would be hard. Since there are several ways to do this (lets just say 5 for this discussion, but there are many more), you would need 5 of the same car, all installed by the same guy using the same amounts of material, then driven and tested over the same roads under like conditions, and probably using a sound level meter to be scientific about it. Otherwise it's all just opinions and hear say. Installers might be able to give the best options, but their experiences can be flawed. Using Dynamat in a big custom van may make a huge difference, but using Q-Quiet in a Camaro might not make as much difference. And even if the installer did do 2 Z's, it would probably be weeks or months apart, and memories aren't always clear with this.

My recommendation after going through all the pain to do it would be not to skimp if you can afford it. Do some research on your own, pick a brand that seems to have a good product, and if they have different options, like thick = $, thicker = $$ & thickest = $$$. Go with the $$$ thickest of that brand and be done with it.

Dynamat has the name, but there are others that are the very similar if not exactly the same, and possibly even better. I chose FatMat because it offered the same sort of product at a cheaper price. If I had to do over I would have bought the better level material though. I just got the regular FatMat, but they make 2 other better ones. My mistake. But if you are considering FatMat, don't use Amazon or the like, because it will cost more. Go direct to FatMat and shipping is free. Also, do NOT buy the trunk kit. #1 it won't be enough, and #2, it's priced higher. If you want to do the entire trunk area, buy the 50 sq ft Bulk package, it's the best deal.
