Since the first month I got my rig in March of '19. I've been tempted to paint mine, it is ugly, visable and it would be very easy to do. It's been on a shelf on the side of the shed since April '19 and I noticed it weathering.

I can stand the ugly look of the silver muffler.
I did this to my first 392, I wrapped it with bronze header wrap and the tips are done in a satin black.
Now that I have my new 392 XR I’m not sure what I’m going to do. It was a lot of time invested in wrapping and painting it, but I think it was worth it
Fire away and let me know what you think about it.
I also was thinking of painting the calipers red
My new 392 XR is a blank slate

Just ask @cosine he knows!
No concerns about higher-than-designed temperatures when painting it black?
You can use BBQ paint, there's also high temp paint specifically made for exhaust parts from brands like VHT

The unsightly mess can be quickly covered by a nice piece of armor, then you just replace the tips.

Thank you but I was referring to the temperature of the muffler itself, not the paint.
I'm not understanding how painting the surface black would raise the temperature of the muffler........it's a thin coat, don't think it has I sulation properties.


As for masking and all that, lol, I just let her howl and go from there. A bit of over spray on my undercoating won't do anything, aesthetically or physically.

There are multiple methods of heat transfer and the concern here would be the fact that black bodies not only absorb thermal radiation the most, they also contain thermal radiation the most. However, this would not have a major effect and it appears many owners are painting their mufflers without issue!:like:

Ya, I think any temperature variation would be negligible at best my friend. It's an OEM muffler. Not exactly built to the tightest of tolerances. Lol.

It certainly looks nice, but it makes me wonder what grade of stainless is used on the factory muffler. There are 2 types used: T304 and T406. The former is better is wet and/or salty environments as it won't rust but it will slightly discolor with heat. The latter is better at holding its silver shine without discoloration from heat but will easily form surface rust in wet and/or salty environments.

The reason I bring up the benefits of each, is because exhaust wrap absorbs and holds water until its cooked off. If the exhaust is made of T406, the wrap will prematurely rot the muffler off of the Jeep. I'd personally just paint it and be done with it. After all, the whole point is to make it visually disappear. So, it doesn't need a lot of effort because it won't be a focal point.

Just my 2 bits.

I understand what you are saying, the drain holes are on the sides of the muffler, it`s made out of 409SS And to each his own. This one I may just paint black, At the time I thought the bronze header wrap would go with the 392's bronze theme, to me the wheels hardly have any bronze to them just the tow hooks really stand out. I have bronze wheels on the Raptor and they are no where near the bronze of the first 392 Rubicon and the same goes with the 392 XR wheels now
I just want to hear every ones opinion and just like yours it makes sense. I appreciate your input, I was also kicking around the idea of powder coating the calipers red, but it may be a little too much
