Frequently Asked Questions

What are the benefits of upgrading my Ford Mustang EcoBoost exhaust?

Upgrading your Ford Mustang EcoBoost exhaust with an aftermarket setup can provide several benefits, such as:

Increased horsepower and torque: Upgrading your exhaust system can increase the flow of exhaust gases, which can increase horsepower and torque. This is especially true in the Ecoboost engines, where increased back pressure can decrease turbo performance. This can result in better acceleration and overall performance.

  • Improved fuel efficiency: A more efficient exhaust system can improve your car's fuel economy improving exhaust flow and reducing back pressure on the engine.
  • Aggressive sound: An upgraded exhaust system can also give your car a more aggressive deep tone and sporty-sounding exhaust note, which can add to the driving experience. Keep in mind to check local, state, and federal noise laws to prevent breaking the law where you live!
  • Better appearance: Upgrading your exhaust system can also improve your car's appearance, especially if you opt for a more stylish or custom exhaust tip than the factory exhaust.
  • Factory Warranty: Most of the time, cat back and axle back exhaust systems do not void Ford’s factory warranty. This means you do not have to worry about taking your car into the dealership with a cat back or axle back exhaust system.

Overall, upgrading your Ford Mustang EcoBoost exhaust can be a great way to improve your car's performance, fuel efficiency, sound, and appearance. However, it's important to make sure that any upgrades you make are compatible with your car's engine and won't cause any issues with emissions or other regulations.

How much should I expect to pay for a quality Mustang EcoBoost exhaust system?

Prices of exhaust systems can vary widely depending on the construction material, brands, type of system, and options the car had when it was built by Ford. For example, down pipes with catalytic converters will be more expensive than down pipes without cats. Also, an aluminized steel exhaust system will be cheaper than 304 stainless steel. Overall you will be spending roughly $500-$2000 for a good exhaust system.

Should I get an axle-back exhaust or cat-back exhaust system kit for my Ecoboost?

Understanding the difference between the two types of systems is key to knowing which is best for your Mustang. The main difference between the two is that the axle-back only replaces the muffler and tips, while the cat-back replaces the exhaust system from the catalytic converter back.

The cat-back is a more comprehensive upgrade, which may provide more performance benefits, including increased horsepower and torque. However, it is generally more expensive than the axle-back.

An axle-back exhaust kit is a good option if you are on a budget and want a simple upgrade to increase the sound. But if you're looking for a more significant performance boost, the cat-back exhaust kit is the better choice.

Remember to keep in mind that Mustangs equipped with factory active exhaust may not be compatible with all cat back and axle back exhaust systems.
