Is there a product that can be painted on joints welded together on exhaust systems to prevent them from rusting out? Mufflers and pipes last a long time but the welded joints seem to rust out fast. Thanks!
No BS. Just have to use the right materials and keep it free of contamination from any ferrous metals. I'm not a welder though so I can't tell you specifics.Interested... I asked my local stainless steel exhaust person, and they said they weld in stainless, so the welds don't rust. It takes a different setup though...
...or he was just feeding me a line of BS.
Stainless generally uses band clamp instead of the u bolt clamp that smashes the pipes together.
Dirty minds think alike.
Well, I find your question has some potential truth behind it, since I am a musician. Wind instruments (which have many similarities to an exhaust system), all have varying tonal qualities which are in part dependent upon the material the instrument is made from. A trumpet made of brass sounds different than one made of silver, or platinum... even when played with the same mouthpiece (where the initial tone is generated that the instrument modifies and amplifies). So it stands to reason the same results might occur with an exhaust system.
In regards to the whether the mufflers for the C-300 or 300B were "stock", in my humble and uneducated opinion there's no way a stock muffler at the time for those cars would have anything but a very slight rumble to it, by design. As I'm sure you agree, since its intended market were well-heeled buyers, it was a luxury car with power, not a muscle car, so anything loud would be considered gauche. I expect the mufflers were not stock. Whether that was exacerbated by the system being made of stainless is something only a comparison test would indicate. All other elements of design (sizes, diametres, pipe thicknesses and component construction techniques etc.) would have to be identical.
SS filler rod is used for TIG welding and SS wire is used for MIG. Never rusts.Interested... I asked my local stainless steel exhaust person, and they said they weld in stainless, so the welds don't rust. It takes a different setup though...
