Are header wraps good ?

[Casa de Mesa]

My V1s are (swaintech white lightning) ceramic coated. I've had them for ~10 years and the coating still looks like new, with lots of track use in the mix.

I don't think there's a ton of benefit, but I don't see any downside whatsoever. Headers are less likely to rust, heat is removed from the engine bay. Good for power, good for longevity of everything in the engine bay. The difference is easily noticeable-- opening the hood of my euro header/cat M3 wagon blasts you with significantly more heat than my V1/swaintech, SS/HJS cat M3 coupe. Both cars have the heat shields in place. Lower temps are good for plastic bits, sensors, seals, etc. Any power bump is just gravy.

Makes me wish I did the Swaintech when I had the headers out of the car.

Will do doing this when I pull the motor.

tape wrap is garbage
but treating the headers with high temp insulator and covering it with stailes i the deal

test shows untreated exhaust part 290 degre celcious has 180 treated this way

I have swaintech coated Megan headers. It definitely helps with under hood temps.

I used header wrap in the section of exhaust that passes under the left inner axle boot to reduce the amount of heat that goes into the CV joint. It's been on there for about 6 years, no extra corrosion under the wrap. The wrap won't absorb much moisture since its fiberglass.
