Aluminized steel is the budget-friendly choice. It has a protective coating that holds up well, but once that coating wears it will eventually rust through, especially in salted winter climates. The stainless option is T409 stainless, an automotive-grade steel built to resist rot, and it will typically outlast the truck. T409 is not polished show-grade stainless, so light surface rust or discoloration can still show up over time. That is cosmetic only and won't affect performance or service life.

• These kits will only fit models equipped with the OEM style 3-bolt flange off the turbo direct pipe!
