Question for you: Is there any benefit to coating these turn downs with the black header coating? Thanks
Yes? And no.
For performance? Are you going for looks or longevity? Do you have the aluminized steel or stainless steel turn down?
Starting with performance- if you're referring to the effect of a ceramic header coating for the purpose of keeping under hood temps down and exhaust gasses hot, then no. I highly doubt coating the cat-back will have the same effects and benefits as what the intended use of a ceramic header coating or "wrap" would have on headers.
Looks- Sure. But in this case some VHT high heat paint, when used in proper applications, can help to protect vital exhaust components. Just make sure to apply and cure it as recommended by the manufacturer.
Longevity? If you have the aluminized turn down and live in a moist area or somewhere in the salt belt then I'd recommend doing something. The VHT is a good idea here too. The muffler and pipes will begin to rust from the inside anyway, so coating the outside may be in vain; but it can't hurt to maintain the outside of your system.
If you have the stainless version - it will not be as susceptible to rust inside and out. The MBRP turn down in particular is T409 stainless steel which is high quality but unlike T304 it will develop some orange discoloration or "surface rust". It's nothing to be alarmed at, the stainless will not rust through but again if the appearance is important then an application of an additional coating could be done. I'd just leave it alone, personally.
I hope I have answered your questions.
