Valvetronic Universal Valved Muffler Kit – Single Inlet Dual Outlet

Do your neighbors despise your cold start in the morning? Do the police give you a hard time because your car is loud? Does your significant other hate riding in your vehicle because the drone is too loud? Maybe you want to make your car a bit noisier with the option to make it sound docile without compromising. Then, the Valvetronic Designs Universal Muffler Kit is the perfect solution for you. Loud when you want, quiet when you need to be, all at the touch of a button!

Key Developments:

This product development was procured from a need to offer a valued experience to all vehicles. Our mufflers give a far more dynamic experience than any other option on the market. Quality is of the utmost importance. Our chambered muffler configuration allows for a quiet, docile experience when the valves are closed. An internal resonance chamber is also built into the muffler to help remove unrefined frequencies from the exhaust. This means you get raw sound and no unwanted frequencies inside the cabin.

Valvetronic Vs. The Competition:

Stemming from the critical developments of the product, there are many reasons individuals worldwide utilize the Valvetronic Designs universal muffler kit. This product offers a much safer and more dynamic experience than a traditional exhaust cut-out. Exhaust cutouts tend to rust, break prematurely, and release harmful gases and heat underneath the vehicle’s center, which is dangerous. This could lead to premature wear of suspension and other components or worse. Valvetronic mufflers are designed to be used throughout the exhaust system and offer a safer experience. Additionally, using vacuum exhaust valves ensures that this kit will last, and you will not have problems with electronic component failure like most of the competition. In our developments, we do not compromise, and neither should you.

For the best effectiveness from the valves open to close, I recommend installing the mufflers with the valve portion facing the rear!
