Variable Displacement Engines and Sound

posted in: V8, Variable Displacement | 4

Your vehicle may have a V8, but it may not always behave as a V8.


Many modern V8s use what’s called “variable displacement technology”. This basically means that the engine will “turn off” certain cylinders when under a light load. These types of engines have become extremely common, and include Chrysler’s “Multi-Displacement System”, GM’s “Displacement on Demand”, and many more.


Variable displacement is a positive thing. It means increased fuel economy, with virtually no tradeoff in performance. It gives you the power you need when you need it, and better MPG when you don’t. What’s not to like?


Unfortunately, there is one drawback- variable displacement technology affects the sound of the engine.


In our personal experience, we’ve found that most performance mufflers sound downright strange on variable displacement engines.


Paradox Performance Mufflers are the exception.


Our mufflers use our patented Tuning Fork Technology, which provides active mechanical noise cancelling. Because our goal is to provide the best performance sound, the tuning forks in our mufflers are engineered to provide the most pleasing sound at the most pleasing times. Besides being resistant to “drone”, Paradox Performance Mufflers are tuned to make variable displacement much more pleasing than is typical.


To be sure, there is still a sound difference. But we would argue that it’s minimal, and even enjoyable. Our dealers tend to agree, to the point of Paradox Performance Mufflers being their only recommended choice for variable displacement.


But don’t just take our word for it. Take a listen to this Chrysler 300C with a 5.7 HEMI V8 with Chrysler’s “Multi-Displacement System”, with Paradox Performance Mufflers.

    I have a Dodge Ram 2500 V10 automatic …. Would like to get better gas mileage … would this muffler make a difference for this vehicle and what is the cost of your muffler?

      Thanks for reaching out, Peggy! We don’t make any official claims about fuel milage, but we have had many, many reports of increased fuel milage, usually in the range of 3 to 6 MPG gains. The pricing for our mufflers can be found at our online store at:

      We don’t currently carry a kit, but this is definitely something that could be easily fabricated at your local muffler shop.
