what does a cat back exhaust do

A cat-back exhaust system is one of the best ways to improve your car’s performance. It replaces the stock cat-back exhaust system and gives your car a more aggressive sound. In also improves airflow and reduces back pressure. As a result, your car will be able to breathe better and produce more power.

What is your EFN # ?

Checking the emission tag under the hood, on the suspension tower, or on the radiator shroud will allow you to determine your car’s EFN.

An aftermarket exhaust system is a practical vehicle modification that can enhance both performance and appearance. Typically, bolt-on kits come in two common configurations: axle-back and cat-back, and can be installed by a novice to skilled do-it-yourselfer. Generally speaking, those who want more sound than what their stock parts produce go for the axle-back option, which will increase overall volume and produce a more aggressive sound. But how do you know which one is right for you? The cat-back is the ideal choice for people who want to boost performance in addition to sound and volume. Follow along below as we dissect the attributes and advantages of each choice to determine which is best for you.

Reason 3: Easy installation

Almost every make and model of car has a cat back exhaust system available, and since they are simple to install, they are ideal for individuals who enjoy doing some do-it-yourself projects.

They don’t need to be modified at all; they just bolt on where the original exhaust is located. The muffler, exhaust tips, and exhaust pipes that come with cat back exhaust systems give you everything you need to replace the exhaust.

Without needing to take out a small loan, cat back exhaust systems are a great way to improve the performance and appearance of your car. Generally speaking, an exhaust can cost anywhere from $300 to $3000.

The materials used—which we will go into more detail about later—as well as the degree of customization you choose—which is also covered below—are frequently the cause of price differences. Here, the key idea is that they don’t have to be extremely expensive.

Reason 8: You’ll be a lot louder

Even though your neighbors might not agree, your car will have a lot more power depending on the muffler you choose, as we’ve already mentioned. This might be the area that requires the most investigation, as each system can have very different sound quality and types.

What is the function of the catback?

Since the cat back system uses the intermediate pipe, it gives better exhaust flow through mandrel bends. The exhaust system uses wider pipes for enhanced exhaust flow, resulting in increased horsepower. Axle back exhaust system is ideal for car exhaust setups that already have pipes with a wider diameter.
