T304 vs T409 Weight

[Yellowjacket]

I hear T304 is lighter than T409. In a full cat-back setup, would the weight be a lb or 2, or more significant?

They should be similar in weight. The only difference is 304 has a higher percentage of chromium and nickel compared to the 409. 304 typically has 20% chromium and 10% nickel and 409 uses around 10% chromium and a lot less nickel, but only enough of both to help ward off corrosion...not the best for salty roads.

304 is a substantially better product if you consider salt on the roads.

Also, 304 is considerably harder so it is not as easy to work with.

409 will weigh much less after 2 years once it starts to break down

That is the truth brother, this is why there are so few manufactures that use 304SS, we take it a step further and ONLY use US sourced 304SS to ensure the highest quality.

For the price difference go with 304.
