Floor & Tunnel Shield II
Great for bus conversions!
"I contacted DEI's customer service and asked what would be the best product to use, and this was recommended. They were a great help and this product was easy to work with. The engine cover is awkwardly shaped, but the tunnel shield was easy to cut and mold to how I needed it. If I need anymore products, this will be the first place I go to!"
Vibration Damping Material
The best upgrade
"Was the best upgrade I could have ever bought at such a low price I wish the store where I had bought the product offered a bigger selection but nonetheless no complaints hands down the best product I have used."
Black Titanium™ Exhaust Wrap Kit
Worth the Money
"This kit is great - I was able to use it to wrap my 1973 Jeep CJ5 headers. I had been having issues with heat on my alternator and wires. This kit solved all that, and looks pretty badass under the hood. I have several friends that have used the same kit for their jeeps since seeing mine."
