Is stainless steel or aluminized exhaust better?
Stainless Steel cost more than Aluminized Steel. Nothing looks better or lasts longer than stainless steel. The aluminized mufflers have stainless internals and necks but have an aluminized outer shell. Also, the aluminized steel has only a protective coating that, if scratched off, may rust.
Is aluminized steel good for exhaust?
Exhaust parts made from aluminized steel have similar properties to mild steel. The difference is that the metal has an aluminized coating. The coating helps resist rust and corrosion. It is more expensive, but will last longer than mild steel.
How long will aluminized steel exhaust last?
In a moderate climate, aluminized steel might last 3-5 years on a daily driver. In a dry climate, an aluminized exhaust system could last 8 years or more.
Does 409 stainless steel rust?
It does not rust easily in wet conditions, is easy to sterilize, and maintains toughness even in hot and freezing temperatures. Due to being weldable and formable, it is easier to manufacture than some other grades. 409 stainless is one of the cheaper stainless steels, and more vulnerable to surface rust than 304.

What is the difference between 304 and 409 stainless steel?
304 is an austenitic stainless steel high in chromium and nickel with very high corrosion resistance. It is one of the most commonly produced and used stainless steel grades. 409 is a ferritic stainless steel with less chromium and very little nickel.
Will a magnet stick to 409 stainless steel?
409 stainless steel can contain up to 90% iron, meaning a magnet will stick to it and is prone to rust.
