Transform the sound of virtually any performance vehicle with the STRATEC™ F1 Universal Valved Muffler Kit, designed for enthusiasts who want a cleaner, more refined acoustic exhaust tone with full control over volume.
Rather than simply making the vehicle louder, the STRATEC™ F1 muffler is designed to improve the character of the exhaust note while allowing you to instantly switch between a quieter, refined sound and an aggressive straight-through performance tone.
Constructed from premium T304 stainless steel with precision TIG welds, this universal system can be integrated into a wide range of custom exhaust applications by a qualified exhaust or fabrication shop.
When the valve is closed, exhaust gases are routed through the muffler's internal baffled chamber.
This helps:
Ideal for cruising, residential areas, highway driving, or whenever you want a more controlled exhaust sound.
Open the valve using the included remote and exhaust gases are directed through the freer-flowing bypass path.
The result is:
Choose the configuration that best suits your exhaust layout:
Traditional inline configuration for single-pipe exhaust applications.
Ideal for converting one exhaust inlet into dual outlets.
Designed for custom exhaust layouts requiring an alternate valve and bypass configuration.
Always measure the outside diameter of your existing exhaust tubing before ordering.
Available as:
Vehicles with true dual exhaust systems will typically require two mufflers depending on the desired installation layout.
The STRATEC™ F1 Valved Muffler is a universal performance component and can be adapted to many:
Because this is a universal product, cutting, welding, fabrication, reducers, adapters, or additional piping may be required depending on the vehicle.
Typical applications may use:
These are general guidelines only. Exhaust diameter should ultimately be selected according to your vehicle's existing exhaust system, horsepower level, engine configuration, and fabrication requirements.
Depending on selected configuration:
Select 1 Muffler or 2 Mufflers according to your exhaust configuration.
When installed as a removable exhaust section and the original factory components are retained, the vehicle can generally be returned to its original exhaust configuration later.
We recommend having the system installed by a qualified exhaust or fabrication shop for the cleanest installation and easiest future reversal.
