Answer:

When dealing with any rust no matter where it is, it is best to treat it as soon as possibly because it will spread, and keep spreading. There are many temporary fixes you could do to spruce up your exhaust tip such as using an sos pad. Gently scrub the rust on the exhaust pipe. This scrub will not damage the pipe, and it actually has rust inhibitor in it to help treat and prevent it from coming back.

Another quick fix would be to try and wax it or use products designed for this kind of problem when dealing with chrome. You could also try to sand it down, treat it when a rust inhibitor, or spray paint it with a paint that already has rust inhibitor in it. There are several at home products you can try to treat rust as well such as using water and tin foil, spraying it with WD-40, etc.

Another way to keep your exhaust tip from rusting is to simply wash your car often. Depending on where you live the winter can take a huge tole on not only exhaust tips, but the whole car. If you are really determined, just keep it clean. You could clean it with just a household steel woal pad too. Or for the really tough spots use a power drill with a specific piece to remove or grind down the rust.

If there are cracks or scratches on the pipe, and it is starting to rust, you will want to get a type of sealant to keep the rust from spreading. You can buy a clear coat paint possibly, a clear sealant, or even use home remedies such as clear nail polish.

As you can see there are several temporary fixes when it comes to exhaust tips and rust. They are designed for looks, so it is truly up to you to ensure they live up to their expectations. Anyone who buys an exhaust tip should know that if they want to keep it well maintained they are going to have to keep up on it. Exhausts get dirty, they get salt on them, mud, etc. The moisture from inside the pipe from the steam causes rust. It is just really something the owner needs to keep up with for it to maintain it's beauty.

You could always try to contact the manufacturer to see if they will give you a refund or send you another tip. It is also important that you know what kind of tip you are getting such as chrome or stainless steel. Stainless steel is not supposed to rust... so if it does, then you must have purchased a chrome pipe. Make sure if you ordered your exhaust tip, make sure you inspect it to make sure there are no cracks or chips where rust can develop before installing it on your vehicle.
