Will this make my car louder?

The role of an Exhaust Controller is to keep the car's exhaust valves open all the way open, all them time and in any mode.

It enhances the exhaust sound within specific RPM ranges / modes / speeds when the valves are normally closed.

It does not increase the maximum volume achievable by the exhaust system (e.g., at full throttle or high RPM when the car's valves are already open), as this would require physical modifications to the exhaust system, such as muffler or resonator delete or modification, or a complete exhaust system upgrade. An exhaust controller can only control the factory exhaust valves. It does not modify or replace the exhaust system.

The controller will get the most out of whichever exhaust system you have as the valves will now be fully open all the time instead of some of the time.

You can check the reviews section for the particular model or the testimonials page for customer feedback!

Sound results depend entirely on:

• Your vehicle’s factory exhaust design
• The vehicle’s valve control programming
• Drive modes, tune mapping, engine RPM, etc.

We are not able to guarantee specific sound increases, tone changes, or performance gains.
