Sound & Control

Valves Open

With valves commanded open, exhaust gases bypass the internal baffles entirely for near-unrestricted flow and maximum volume. The chambered muffler design ensures the open-valve tone remains clean and aggressive — free of rasp and unrefined frequencies — whether installed on a V8 muscle car, a turbocharged four-cylinder, or a performance SUV.

Valves Closed

Close the valves and exhaust gases are forced through the internal chambered and packed pathway, dropping volume to stock-like levels with zero drone. The resonance chamber eliminates unwanted cabin frequencies, delivering a refined, quiet driving experience that preserves the comfort of daily driving.

Installation

Universal fitment — welding is required to install the mufflers inline with your existing exhaust. For optimal valve operation, install each muffler with the valve side facing the rear of the vehicle. Connect vacuum lines from each muffler to the included vacuum control box, and wire the control box to a 12V power source using the included cigarette lighter adapter or hardwire connection. No drilling required. As a universal product, the purchaser is responsible for confirming fitment compatibility before ordering.

VALVETRONIC DESIGNS

Valvetronic Designs Universal Valved Muffler Kit

On-Demand Exhaust Control for Any Vehicle — No Custom Fabrication Required

The Valvetronic Designs Universal Valved Muffler Kit brings professional-grade exhaust valve technology to virtually any vehicle regardless of make, model, or exhaust configuration. Available in 2.5-inch and 3-inch pipe diameters, each kit includes a pair of chambered mufflers with integrated exhaust valves, a vacuum control box, vacuum lines, a wireless key fob controller, and a power adapter for straightforward installation. The mufflers are constructed from the highest quality T304 stainless steel with precision TIG welds, and the internal chambered design incorporates a resonance chamber that filters unrefined exhaust frequencies — meaning you get a clean, raw tone when the valves are open and genuine stock-like quiet when they are closed.

The vacuum control box operates the valves on command, creating the vacuum pressure needed to open and close the valve assemblies reliably and repeatedly. Installation follows the same workflow as any muffler replacement: position the mufflers in-line with your exhaust path (valve side facing rearward), weld into place, and connect the vacuum lines to the control box. No drilling is required, and the included cigarette lighter power adapter allows for easy hardwiring into any 12V system.

This is the most accessible way to add true valved exhaust control to any car, truck, or SUV — delivering the same on-demand dual personality that vehicle-specific Valvetronic systems provide, at a fraction of the cost and with universal compatibility.
