Is the stock exhaust system aluminized steel or stainless?  I am thinking about getting different mufflers to replace the stock ones and if its steel I can weld it myself.

Pretty much every single factory exhaust is 409 stainless steel.  It's a ferritic alloy, which means is chromium base with iron to balance out the mixture, with great corrosion resistance and heat expansion properties for automotive use. 

Aluminized steel is standard carbon steel with an aluminum coating.  It's junk material used on beater cars as replacements when the stock exhaust is damaged.
