Black Bandit Exhaust Comparison: 409 vs. 304 Stainless Steel

Choosing the right exhaust system is like picking the best partner for your car. Performance, durability and appearance all matter.

Tuner Depot has two options for your exhaust system. The first is the Black Bandit Standard (409). The second is the Black Bandit Series III (304).

Each comes with its own personality, strengths, and quirks. Let’s take a closer look at what makes them unique.

Black Bandit Standard (409) Stainless Steel

The Black Bandit Standard exhaust is like the reliable workhorse of the family. Made from 409 Ferritic Stainless Steel, it’s a solid choice for many drivers. Here’s why:

Material Composition: This exhaust system is made with up to 90% iron, plus chromium (10.5%-11.75%) and a little nickel (up to 0.5%). The high iron content makes it magnetic—just a fun fact if you ever want to stick a magnet to your exhaust.
Rust Resistance: Rust isn’t its best friend. The 409 is moderately resistant but can develop surface rust, especially after heat. While this rust doesn’t affect the performance, it does impact the look. If you’re not too worried about the shine, this could work for you.
Durability: Expect it to last around 5-8 years, depending on how you use it. A great option for standard applications exists, especially if you’re not putting your exhaust through extreme paces.
Aesthetics: Looks aren’t its strongest point. Over time, it tends to turn dull and may even get a brownish tint after a lot of heat exposure. But if you're more about practicality and less about the flash, the 409 is a cost-effective choice.

Black Bandit Series III (304) Stainless Steel

Now, if the 409 is the workhorse, the Black Bandit Series III is the racehorse—sleek, shiny, and built for endurance. Made from 304 Austenitic Stainless Steel, it’s the high-end option for those who want the best. Here’s what makes it stand out:

Material Composition: This material has 18% chromium and 8-10% nickel. It has less iron, which makes it non-magnetic. The chromium and nickel make it much better at resisting rust.
Rust Resistance: The Series III is tough against rust, even in tough conditions. Sure, very salty environments might affect it eventually. However, it is much more resilient than its 409 sibling.
Durability: This exhaust, designed for heavy-duty and high-performance applications, lasts up to 20 years. If you’re looking for something that’ll stick around for the long haul, 304 is your go-to.
Aesthetics: Looks-wise, this exhaust shines—literally. It stays shiny and even develops a cool golden hue over time with heat. To make your exhaust look as good as it performs, this is the one for you.

Which Exhaust System Is Right for You?

So, which one should you choose—the workhorse or the racehorse?

If you’re after something affordable that gets the job done without worrying too much about aesthetics, go for the Black Bandit Standard (409). It’s reliable, functional, and won’t break the bank.
If you’re all about performance, durability, and want something that looks fantastic too, then the Black Bandit Series III (304) is the better choice. It’s made for those who demand more from their vehicles—both in looks and longevity.
