Silly question: Powder coating an exhaust???

So long time lurker, first time poster.

Recently upgraded from a 05 DCLB Prerunner to a 19 DCLB OR and gotten bite by the mod bug.

Was looking around just preliminary and saw some budget friendly MBRP exhaust for under $300 and saw their reviews about them starting to rust within a few months in snow/salt areas.

Does anyone have experience with powder coating their exhaust to lessen the chances of rust/corrosion???

Thanks in advance!

 

Won't work. The heat will melt it off pretty quick. It will smell pretty bad until its all melted off as well. Think what a trash fire smells like.

 

Powder coating shops have other coatings that they can put onto exhausts. Chrome like, black, etc and they are very nice. I don't think powder coating works due to the elevated temps on the exhaust.

 

most powdercoating operations will also ceramic coat. I've done it on multiple vehicles

 

Don’t waste your money...as the powder or ceramic coating is only as good as the surface it’s bonded too...it’ll just rot from the inside out.

 

Why not just paint it with vht? Then you can wash and touch up as needed. Can't effectively touch up a baked on finish like powdercoat on the vehicle.

 

Ceramic coating is an option, but I'm sure it's $$$ and you need to do inside and out. I have ceramic coated headers on my Camaro and they still look almost new after 15 years.

I wouldn't bother. Nothing wrong with stock exhaust spend the $$$ on mods that actually do something

 

Aside from keeping them looking new, do you think the coating effectively lowered under hood temps? I'm considering doing it to a set of manifolds and exhaust on my '49 chevy w/ 350 sbc.

 

Why not just save the powder coat money and buy a different system? Why reward that behavior?

 

Unless you can coat the inside of the pipe, there will not be full coverage of the exhaust. The clean burning engines today produce water, hence the condensation you get when first starting up.
Unless you go full titanium exhaust, or stainless. Common steel will always oxidize eventually.
