Default chrome downpipe

hey whats up guys i was wondering if it would be a good idea to chrome my downpipe (its mild steel 4in diameter takes up half the engine bay so yeah this thing has gotta look good) in other words if i chrome my downpipe will it turn colors and look all crappy. What are my other options to get my downpipe a polished look ive thought of converting to stainless and polishing it but id don't have experience with this high temperature stuff

A high temp ceramic coating will hold up much better than chrome.
The high EGT's of a turbo engine will discolor the chrome in a hurry.
Talk to a good coater to see what he can do for you.
I have heard that there are very bright silver coatings available, but they will only hold up if the inside of the pipe is coated with the high temp insulating black.
I don't have the names of the coatings, but I am sure a professional coater will know the best products to achieve the desired result.

Good luck!

You need stainless or aluminum to get a polished look you want.

You can't use aluminum for exhaust tubing. Stainless will turn brown once it gets hot. He needs ceramic high temp coating and it will look nice

Ok, so I wouldn't use it on a street car. I guess with an open down pipe, track car, you could use it, but that's about the only way I would use it. Can't see it having a long life in daily driver boosted car.

The stainless can be repolished after it is heated up and it will shine up again.

I dont believe anyone makes a high enough temp silver color that people are used to seeing on headers, it will dull and fade over time. There is a high temp black coating, but thats not what you are looking for.

I think you can take care of it by just repolishing, dont think any sanding is needed.
