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 just want to make your car a bit louder 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! Why is Valvetronic Designs' Universal Valved Muffler Kit Different?

Key Developments:

This product development was procured from a need to offer a valved 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. Additionally, an internal resonance chamber is built into the muffler to help remove unrefined frequencies from the exhaust. This means you get only raw sound and no unwanted frequencies inside the cabin.

Valvetronic Vs. The Competition:

Stemming from the key developments of the product there are many reasons individuals from around the world utilize the Valvetronic Designs universal muffler kit. Compared to a traditional exhaust cut-out, this product offers a much safer and more dynamic experience. Exhaust cutouts have the tendency to rust, break prematurely, and release harmful gases and heat underneath the center of the vehicle which is very dangerous. This could lead to premature wear of suspension and other components or possibly worse. Valvetronic mufflers are designed to be used throughout the exhaust system and offer a safer experience. Additionally, the utilization of 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.

Here is how it works:

Mufflers come with a vacuum control box and vacuum line allowing for an easy install. The mufflers install just like any muffler, but plug in the valves with the supplied vacuum tubing and BOOM! you can now control your car's sound on the fly. In the past, this technology was reserved for supercars but not anymore.

Warranty:

Valvetronic Designs Universal Valved Muffler Kits come with a 1 year warranty. Details about this warranty can be found on our Return and Shipping page.
