What is the main difference between a resonated and non-resonated exhaust?

A resonated exhaust includes a resonator chamber designed to cancel out some of the harsher frequencies, resulting in a quieter, smoother tone. A non-resonated exhaust skips this chamber, leading to a louder, more raw, and aggressive exhaust note.

What material is the GReddy DD-R exhaust made from?

This exhaust system is constructed from stainless steel. This material is chosen for its strength and its ability to resist corrosion, which is important for components exposed to exhaust heat and road conditions.

Does this exhaust system come with all the necessary hardware for installation?

Typically, cat-back exhaust systems are designed to utilize existing factory hardware where possible. While this system is a direct bolt-on, it's always recommended to consult the manufacturer's installation instructions or contact us to confirm if any specific additional hardware is required for your vehicle.

Product Details

GReddy is well-known for making performance exhaust systems that really let your engine breathe. This DD-R Non-Resonated Cat-back exhaust is built for the 2017 and newer Honda Civic Sport 5DR and Type-R models, aiming to give you a more aggressive sound and improved exhaust flow. If you're looking to change the character of your Civic's exhaust note and unlock a bit more performance, this system is designed to do just that.

This exhaust system is constructed from durable stainless steel, which is a solid choice for resisting corrosion and handling the heat under your car. The 'Non-Resonated' design means it skips the resonator, which typically results in a louder, more direct exhaust tone compared to systems that keep it. This setup is part of GReddy's DD-R line, suggesting a focus on a bold sound profile. The cat-back design means it replaces the exhaust from the catalytic converter back, making it a comprehensive upgrade for the rear section of your exhaust.

When installing this system, you can expect a direct bolt-on fitment, meaning no welding or cutting is typically required, simplifying the installation process. It's designed to integrate with your Civic's existing exhaust layout from the catalytic converter forward. This exhaust is a popular choice for owners who want a noticeable change in their car's sound and a more performance-oriented feel.
