Some Factors You Should Know About Axle-Back Exhaust Systems

Introduction

When it comes to upgrading your vehicle's exhaust system, one of the most popular options is the axle-back exhaust. This type of exhaust system replaces the section of the exhaust that runs from the rear axle to the back of the vehicle, improving the sound and performance of your vehicle. But with so many options available, choosing the right axle-back exhaust system can be overwhelming. In this article, we'll discuss some key factors to consider when choosing an axle-back exhaust system for your vehicle.

Material

One of the first things to consider when choosing an axle-back exhaust system is the material it is made from. The most common materials used in exhaust systems are stainless steel and aluminized steel. Stainless steel is a durable and corrosion-resistant material that is ideal for long-term use. Aluminized steel is a less expensive option that is also resistant to rust, but it may not last as long as stainless steel. When choosing a material, consider the type of driving you do and the conditions your vehicle will be exposed to.

Sound

One of the main reasons people choose to upgrade their vehicle's exhaust system is to improve the sound. Axle-back exhaust systems are available in a range of different sounds, from mild to wild. Consider the type of sound you want from your exhaust and choose a system that matches your preferences. Remember that loud exhausts can be illegal in some areas, so be sure to check your local laws before making a decision.

Fitment

Another important factor to consider when choosing an axle-back exhaust system is fitment. The exhaust system must be designed to fit your specific make and model of vehicle for it to work properly. Be sure to choose an exhaust system that is designed for your vehicle to ensure a proper fit. If you're unsure about the fitment, check with the manufacturer or a trusted mechanic for advice.

Price

Of course, price is always a factor when making a purchase. Axle-back exhaust systems can range in price from a few hundred dollars to several thousand dollars, depending on the material, brand, and other factors. Consider your budget and choose a system that fits within your price range. Keep in mind that high-quality exhaust systems may cost more upfront, but they may last longer and provide better performance in the long run.

Conclusion

Choosing the right axle-back exhaust system for your vehicle can be a challenging decision. By considering factors such as material, sound, fitment, and price, you can narrow down your options and choose the system that best meets your needs and preferences. With the right exhaust system, you can improve the sound and performance of your vehicle, giving you a more enjoyable driving experience.

Frequently Asked Questions (FAQs)

1. Is axle back exhaust worth it?

Axle-back exhaust systems typically don't significantly improve performance. While they can free up airflow by replacing the muffler, the gains are usually minor. However, they are relatively easy to install as they replace only a small section of the exhaust system.

2. How much HP does an axle back exhaust add?

The right axle-back exhaust system can add gains of up to 30-35 HP for many cars like Mustang, Challenger, Camaro, and Corvette. It can enhance performance and fine-tune torque. The exact increase in horsepower can vary depending on the specific car model.

3. Does an axle back exhaust require a tune?

Axle-back exhaust systems do not require an updated tune because they do not affect the engine's aspiration or require changes to sensors or meters. They primarily enhance sound and may allow for increased airflow, but they do not impact the engine's performance in a way that requires a tune.

4. Is axle-back or cat-back better?

Cat-back exhaust systems typically offer more performance benefits compared to axle-back systems. Cat-back systems include components like mid-pipes, mufflers, tailpipes, and exhaust tips. They have larger diameter, mandrel-bent tubing that improves airflow efficiency, resulting in greater performance gains.

5. Is an axle back exhaust loud?

Axle-back exhaust systems can increase the overall volume and produce a more aggressive sound compared to stock parts. They are a popular choice for those seeking a louder exhaust note. However, if you want both increased sound/volume and performance, a cat-back exhaust system would be a better option.

6. What is louder, cat-back or axle-back?

A cat-back exhaust system is typically louder and more aggressive than an axle-back system. While both options can provide a deep and exhilarating exhaust note, the improved airflow in a cat-back system results in a louder sound.

7. Do axle-backs change the sound?

Yes, axle-back exhaust systems can change the sound of a vehicle. They can increase the overall volume and produce a more aggressive exhaust note compared to stock parts. They are a popular choice for those looking for a more pronounced and distinct sound.

8. Is a muffler delete louder than an axle back?

A muffler delete is generally louder and raspy compared to an axle-back exhaust system. The absence of a muffler in a muffler delete system results in a louder and more aggressive sound. Conversely, an axle-back system with a muffler will have a smoother and more mellow sound.
