Any idea what you could do to new exhaust that you could purchase locally that would make it last noticably longer? This could be done before installing it. I know of high heat paint but not sure if that would truly help.

If you get stainless steel, it would be more expensive, but it would likely outlast the car

I believe the factory system is stainless, what is wrong with yours?

The factory is standard galvanized, therefore the replacement would be the same. It'* not stainless therefore I want it to last about 7 years.
