Stainless vs Aluminized
Stainless vs Aluminized
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.
Notes
Notes
- Some older Duramax trucks have a V-Band Style Clamp rather than the 3-bolt flange. This kit ONLY will work with the 3-Bolt Flange Style off the turbo direct pipe
