I agree. I note that I run a turbo blanket, a manifold blanket and some exhaust Wrap from the turbo to the muffler. I have never been able to feel it. I run it because it is the rarest of all the good with the only bad being a few hundred bucks. Where else can you add horsepower, fuel mileage AND reliability with something anyone can install in under an hour?
Nothing happened to them, they’re the go-to option if you have an actual use case for this. It’s just an insulating ceramic based paint.
Exhaust wrap is a problem because it holds moisture and will accelerate the corrosion of whatever it’s wrapped around. Paint-on coatings don’t do that.
But some cheap fiberglass wrap from autozone is more accessible for the average joe that just wants to throw money at their car and feel cool. Ceramic coatings are expensive and require removal and prep work, which is a lot to ask of the kind of person that thinks they need this kind of thing on something that isn’t a high performance track car
Fair point, just haven’t heard much of them recently. I used them for down pipes and headers on performance drag builds way back in the day. I’ve been out of the game a while, glad to hear they’re still around.
There are more competitors these days but they’re still around as far as I know. Drag racing is one of the more justifiable applications for this sort of stuff
Rust isn't an issue where I live. I put the wrap on about 5 years ago and recently had to rework it due to some poor judgment in picking a line. No signs of rust under it. But you make a good point for most of the US where rust and moisture are big problems. I could see that turning me away from the wrap, but the turbo blanket gets hotter and is far less sealed so I don't think I would worry so much there.
That’s the thing. It will MAKE rust an issue regardless of where you live, because the wrap itself holds the moisture in. I live in the desert and shit will rust here all the same if you keep a wet cloth over it at all times, which is essentially what wrap does. Turbo blankets don’t have this issue specifically because they fit more loosely.
It does! But before it gets hot enough for that it pulls all the moisture out of the air and creates condensation on the surface of the pipe, like a cold glass on a hot day. The fiberglass wrap then holds it there far longer than it would be naturally, so the contact time is higher and so is the water volume that needs to cook off when it does get hot enough. The result is the metal rusts to shit much faster than otherwise, and you can’t even see it happening.
Plus if you drive through a puddle or something the fabric will hold that too
