Are Cat Back Exhausts Legal

There’s a lot of debate out there about whether or not cat back exhaust systems are legal. Some people say they’re illegal because they don’t meet emissions standards, while others claim that they’re perfectly legal as long as the catalytic converter is still in place. So, what’s the truth?

Are cat back exhausts legal or not?

If you’re considering upgrading your car’s exhaust system, you might be wondering if a cat-back exhaust is legal. The answer depends on a few factors, but in general, cat-back exhausts are legal as long as they meet certain criteria. First, it’s important to understand what a cat-back exhaust is.

A cat-back exhaust is an aftermarket exhaust system that replaces the section of piping between the catalytic converter and the muffler. Cat-back systems are often more performance-oriented than stock exhausts, and they can provide a significant boost in power and sound. However, because they replace part of the emissions control system, there are some restrictions on what types of cat-backs are legal.

In the United States, for example, the Environmental Protection Agency (EPA) has regulations on aftermarket exhaust systems. These regulations vary from state to state, but in general, an aftermarket system must not increase emissions beyond what the vehicle was originally designed for. So, if you’re looking at installing a cat-back on your car, make sure to do your research first.

Check with your local laws and regulations to see what type of system is allowed.

Are Cat Back Exhausts Legal in All 50 States

Most car enthusiasts know that a cat-back exhaust system is an aftermarket upgrade. But, did you know that these systems may not be legal in all 50 states? That’s right, depending on your state’s emissions laws, a cat-back exhaust system may not pass inspection.

So, what exactly is a cat-back exhaust system and why might it not be legal in your state? A cat-back exhaust system replaces the factory catalytic converter and muffler with aftermarket parts. These parts are often larger and more aggressive sounding than the stock parts.

While this may make your car sound better, it can also make it louder. In some states, this increased noise level may make your car illegal to drive on public roads. Additionally, many cat-back exhaust systems do not include a new catalytic converter.

This means that they will not reduce emissions as much as the factory parts. As a result, these systems may not pass state emissions inspections. Even if your state does not require emissions testing, you may still run into problems if you are pulled over by the police for excessive noise levels.

So, before you buy a cat-back exhaust system, check your state’s laws to see if they are legal where you live. You don’t want to end up with a ticket or having to replace your brand new exhaust system!
