Custom Stainless Steel Exhaust System Guide

When upgrading your exhaust system to a custom aftermarket system, you want to be sure you're using the right materials for the job. And with all the components that make up an exhaust system (like the exhaust manifold, catalytic converter, tailpipe, and muffler), it can get overwhelming.

One of the questions we often get asked at the Performance Muffler is what role stainless steel plays in your exhaust system. And that's what we're going to dive into in this article.

Why make a custom exhaust system at all?  

First, you might be wondering why it's worth making a custom exhaust system at all. After all, your car works great when it leaves the factory, right? Sure, but it could be much better with customization. A custom exhaust system offers several benefits. To name a few, it will increase power, sound and fuel economy. We recommend making a custom exhaust for most drivers. You will improve your car and make it more personal.

Is stainless steel suitable for exhaust gases?

Stainless steel is great for an exhaust system for several reasons. At first glance, stainless steel gives your car a nice aesthetic look. The material is well suited for forming pipes, which makes it easier to move around the vehicle.

In addition, most stainless steel alloys in vehicles can withstand extremely high temperatures. As you can imagine, it gets hot under the hood of your car. The better the tube can withstand these temperatures (combined with pressure changes), the longer the exhaust lasts. Stainless steel is also more resistant to corrosion because it has less carbon. It has greater strength, appearance, and affordability than other materials, making it the smart choice in every way.

Which stainless steel is best for exhaust?

Now that you understand why stainless steel is exceptional for your vehicle, let's analyze which grade of stainless steel is best. There can be many varieties, but the most common are 304 and 409 stainless steel. The difference between the two is the amount of chromium and nickel in each.

304 stainless steel contains more chromium and nickel. In particular, 304 has 18-20% chromium and 8-10% nickel compared to 409 with 10.5-12% chromium and 0.5% nickel. So 304 stainless steel is a higher quality material, making it the best choice for your exhaust system. Grade 304 is also harder to bend and cut, so we recommend that you leave your exhaust pipes to the professionals.

What do I need to make a custom exhaust?

As a reminder, "custom" exhaust really means any aftermarket modification to a standard or factory exhaust system. This can range from replacing your exhaust tips or adding exhaust manifolds. Or, of course, a custom exhaust could include a complete rebuild, such as fitting a closed-loop exhaust system.

So the answer to What do you need for a custom exhaust? also varies. If you want to change the exhaust pipe, you definitely need to understand how MIG welding is different from TIG welding. Changing the exhaust is a task that requires specialization and time; don't cut corners in the process. You can even make it easier by seeking professional automotive advice or service.
