Build-Your-Own Universal Vacuum-Actuated Valved Mufflers Kit

One of the most important steps in building a custom exhaust is choosing the correct muffler. It is crucial to get the correct amount of volume and tone when choosing a muffler. The ECS Tuning Valved mufflers makes this choice easier by giving you the best of both worlds. Close the valves for comfort and open up the valves when you want to hear the intoxicating exhaust notes of your custom exhaust!

These valved mufflers use the same tried and true design that is used in several ECS Tuning exhaust that our customers have come to love.
