TTI Exhaust Longevity

My exhaust isn't TTI, but it is aluminized. I drive about 2000 miles per year and get caught in the rain at least once per year. I have had the pipes since 1995 and they still look like they were just installed (Ican't say the same for my steel, uncoated headers). I store in an unheated garage in the winter.

I think you will be happy with them.
