How much do you need? Figure it's about an inch thick uncompressed. I've previously bought it in bulk, so I'm sure I have some of the real deal left over--I could send you some for evaluation.

Wow! Thanks for the offer. I'd need probably a couple of sq ft to try it. One layer would not fill the space between the center tube and the canister (2" center tube & 4.5" OD), and the muffler section is ~10" long. I'll PM my address.
