Aluminized exhaust pipe vs stainless steel. The aluminized coating will protect the metal from rusting. In a moderate climate aluminized steel might last 3-5 years on a daily driver. Being in Alabama the exhaust will most likely rust from the inside out due to condensation so an external coating wont help a lot with that. Exhaust parts made from stainless steel have the best resistance to rust.
Chrome on the other hand has its share of problems too. Also polished stainless will turn gold. The stainless steel exhaust system on the other hand is covered with chromium nickel and manganese as to create corrosion resistance alloy. Areas that scrape over a curb or get dinged by rocks will rust just like mild steel.

Exhaust parts made from stainless steel have the best resistance to rust. Nobody carries 304 stainless but TTI. It is commonly used for automotive exhaust components exhaust tube exhaust pipe heat exchangers in residential furnaces commercial rooftop HVAC units automotive mufflers. Although aluminized steel is the better of the two money-wise.
Will the stainless weld okay to the aluminized using 7525 or maybe even flux core or am I asking for trouble.
Stainless steel is the most.
Exhaust parts made from stainless steel have the best resistance to rust.
The aluminized piping i put on all the big rigs usally last 2-3 years on thier trucks.
Although stainless steel is the stronger of the two aluminized steel has a greater electrostatic surface and can therefore reflect heat better.
A common problem with aluminized steel exhaust is rusting from the inside out.
