Are those after market pipes?
Double walled Honda stock pipes that is almost impossible to discolor that bad.
If they are stock pipes, someone ran the choke, enrichener, way way way too long...
Ya'll will need a lot of elbow grease to clean those up. If it was me, I'd take them to a powder coater and have em coated. Like these pipes on the Chevy.
Headers are ceramic, the mufflers are powder coated. The yellowish link in between the header and muffler is a chrome piece that yellowed out.
