This wool mat is made from the same materials as OEM but is wired through all seams with 316 stainless wire. This wire exits the seams in specific places for easy installation. Once the mat is placed around the elbow, simply twist wires together until tight.
This is a non-OEM, aftermarket part HDI-MAT4.
