If you rough up the mufflers, you are going to remove some of the rust inhibitors applied.That will look nice. Remember, mufflers are galvanized and paint will not easily stick to it. Rough it up some with some sand paper, apply heat rated primer and header paint to get a long lasting result.
Spot on, my probe was wayyyyy under 300 Degrees. So, I'm now dipped!If you rough up the mufflers, you are going to remove some of the rust inhibitors applied.
That far down the exhaust, the muffler and tip (assuming that's all that is needed) is likely under the 300oF temperature limit for plastidip. I plastidipped my muffler tips on my Ram ages ago, and it still looks like day one and I can peel it and the chrome underneath is completely intact, as would be the protective zinc on the stock muffler.
I'd run the vehicle hard and then run a temp probe on it, it may be safe.

Good to know. There is some heat shielding around it, so it gets hot, but not header hot. I still used high temp header paint...Spot on, my probe was wayyyyy under 300 Degrees. So, I'm now dipped!
