I installed a Fresh Air Exhaust to my 2017 Craz expect the same noise reduction as my previous Moombas, however this was not the case. This Craz was still loud as hell even with the FEA, we'd still have to yell over the engine noise or turn up the music volume. Not what I wanted.

I was pretty skeptical about the amount of noise reduction from installing Dynamat, but overall it really seemed to help.

The Dynmat adds heft/thickness/sound deadening to the engine compartment.


1. Removed the carpet from the backside of the bench seat engine compartment.
2. Installed 2 layers of Dynamat, then 1 layer of Dynapad, then reinstalled the carpet using contact cement.
3. Repeat the same layers for the lower bilge access panel - (This is where a lot of noise comes from).
4. Used the leftovers to cover the engine panel dividers.

$278.24 for the materials and 2-3 hours for the install.
