Frequently Asked Questions (FAQs)

1. Do axle back exhausts improve performance?

Axle-back exhausts primarily enhance the sound and volume of your vehicle, providing a more aggressive tone. However, for those seeking both improved sound and performance, a cat-back exhaust system is the better option.

2. Does axle back exhaust increase horsepower?

Yes, axle-back exhaust systems can increase horsepower by up to 30-35 HP for certain cars, such as Mustangs, Challengers, Camaros, and Corvettes. These performance gains can significantly enhance your car's overall performance.

3. Does an axle back exhaust make a difference?

Axle-back exhausts mainly focus on enhancing the sound of your vehicle and do not improve exhaust flow. If you want to improve exhaust flow without expensive modifications like headers or catalytic converter removal, a cat-back exhaust system is recommended.

4. Does an axle back exhaust require a tune?

No, axle-back exhaust systems do not require an updated tune. They do not affect the engine's aspiration and are designed to be compatible with the vehicle's existing sensors and meters.

5. Which is louder, catback or axle back?

A cat-back exhaust system provides deep, exhilarating exhaust notes similar to axle-back systems, but with improved airflow, resulting in a louder and more aggressive sound.

6. Is axle-back exhaust bad for your car?

While axle-back exhaust systems may slightly reduce fuel economy, their impact on the overall performance of your car is not significant. However, for optimal performance gains, a cat-back exhaust system may be a better choice.

7. Does installing an axle back exhaust void warranty?

Contrary to popular belief, installation of an aftermarket axle-back exhaust system does not void the entire vehicle warranty. It may affect the warranty only for the specific parts and systems directly affected by the modification.
