Are Cat Back Exhaust Legal?

There are a lot of people out there who love the sound of a roaring engine. For some, it’s the only thing that gets them going in the morning. But for others, the sound is just too much to handle.

That’s why many states have laws against excessively loud exhaust systems on cars and trucks. But what about cats? Are they legal?

The answer is yes, cat back exhaust systems are legal in most states. However, there are a few things you need to keep in mind before you install one on your car or truck. First, check your local noise ordinances to make sure your car will be within the legal limit when you’re driving around town.

Second, be aware that some states have emissions testing requirements that could prevent you from registering your vehicle if it doesn’t pass inspection with a cat back system installed. Finally, make sure you know how to properly install and maintain your new exhaust system so it doesn’t cause any damage to your vehicle or void your warranty.

There are a lot of people out there who love the sound of a roaring engine. For some, it’s the only way to travel. But when it comes to exhaust systems, is louder really better?

And are so-called “cat back” exhausts legal? First, let’s define what a cat back exhaust is. A cat back system includes everything from the catalytic converter back – that is, the parts of the exhaust system after the catalyst.

Cat back systems are usually seen as an upgrade from stock because they offer more power and a deeper, more aggressive sound. Now, as for whether or not they’re legal… it depends on where you live. In some states and provinces, there are laws governing noise levels for vehicles on public roads.

As such, many cat back systems come with optional mufflers or tips that can help keep things within the bounds of the law. That said, it’s always best to check with your local authorities to be sure before you make any modifications to your vehicle. So if you’re looking to add a little growl to your ride, a cat back exhaust system may be just what you’re after.

Just be sure to do your research and stay safe (and legal)!

Are Cat Back Exhaust Legal in Pa

Most people are familiar with the deep, throaty rumble of a muscle car or motorcycle with a modified exhaust system. But did you know that those same modifications could be illegal in Pennsylvania? That’s right – if your vehicle has been modified to produce excessive noise, it could be considered a public nuisance and subject to fines.

So what exactly is considered excessive noise? The Pennsylvania Department of Environmental Protection (DEP) defines it as any sound that exceeds the ambient noise level by more than 5 decibels. In other words, if your car or motorcycle is significantly louder than the surrounding environment, it could be in violation of state law.

One way to measure ambient noise levels is with a sound level meter, which can be purchased online or at many hardware stores. DEP also has a free smartphone app called PA Sound Check that allows users to measure ambient noise levels and compare them to state standards. If you’re not sure whether your vehicle’s exhaust system is too loud, you can always have it tested by a certified mechanic.

Many garages and auto shops offer this service for a fee, and DEP also operates several testing facilities across the state. Keep in mind that even if your vehicle passes inspection, you could still be cited for excessive noise if it disturbs the peace or causes a safety hazard. So use common sense when operating your vehicle – if it’s too loud for conversation or sleep, chances are it’s too loud for the law.

Are Cat-Back Exhaust Loud?

If you’re looking for a way to make your car louder, a cat-back exhaust is a good option. This type of exhaust replaces the muffler and piping from the catalytic converter back to the end of the tailpipe. As a result, it can make your car significantly louder than stock.

There are a few things to keep in mind if you’re considering a cat-back exhaust. First, this type of modification is not legal in all areas. Be sure to check your local laws before making any changes to your car’s exhaust system.

Second, while a cat-back exhaust will make your car louder, it won’t necessarily improve performance. In some cases, it can even slightly reduce power output. If you decide to install a cat-back exhaust, there are several different types to choose from.

Each has its own benefits and drawbacks, so be sure to do your research before making a purchase. With that said, here are a few of the most popular options: • Glasspack: A glasspack is one of the cheapest and easiest ways to modify your car’s exhaust system.

It simply replaces the muffler with an empty chamber that allows noise to exit without being dampened by fiberglass packing material. Glasspacks are very loud but don’t offer much in terms of performance gains. • Straight pipe: A straight pipe eliminates the muffler entirely and connects the catalytic converter directly to the tailpipe.

As such, it offers significant weight savings and improved airflow but is incredibly loud – often too loud for street use. Straight pipes are also not legal in all areas due to their excessive noise levels.

If you’re looking for a CARB legal cat-back exhaust system for your vehicle, there are a few things to keep in mind. First, check with your local emissions testing station to see if they require a CARB sticker on your vehicle before it can be registered.

Second, make sure that the system you’re considering is listed on the CARB website as an approved product. Finally, be aware that installing a non-CARB compliant exhaust on your vehicle may result in penalties from both the DMV and law enforcement.


There are many factors to consider when deciding if a cat back exhaust is legal or not. The first is the type of vehicle you have. If you have a street car, then the answer is most likely yes, a cat back exhaust is legal.

However, if you have a race car, then the answer is more complicated. Race cars must meet certain regulations in order to be legal on the track. These regulations vary from country to country and even from state to state.

There are also different classes of racing, which further complicates things. Next, you need to consider what type of racing you will be doing. If you are just going to be driving around town or on the highway, then again, a cat back exhaust is probably fine.

But if you plan on taking your car to the track and racing it competitively, then there are stricter rules that apply. For example, many tracks require that all cars have mufflers in order to reduce noise pollution. So if your car doesn’t have one already installed, adding a cat back exhaust might not be allowed.

Finally, it’s important to check with your local laws and regulations before making any modifications to your car’s exhaust system. Depending on where you live, there could be restrictions on how loud your car can be or what types of modifications are allowed. So it’s always best to err on the side of caution and check with authorities before making any changes to your car that could potentially get you in trouble later down the road.
