1999-2007 GM Heat/Sound Insulator Firewall

I gave it a try

I was out a firewall insulator and hadn’t ever really had to deal with specifically that type of issue. I was determined to put in the work save the money and just create one myself. And I most likely could have, but I ordered one just because I had a good feeling about it and it’s pretty straightforward. The product is what they describe it as. Certain areas can be a pain but installing this without pulling half of your bay out or even your motor is a breeze. It’s made of some quality materials, ships super quick and looks great in the duramax. If you’re thinking about it because you need one the. This is what I would recommend. Fast, affordable, easy to work with. Pretty cool product and pretty cool company engineering all of this.
