Laminar Flow Mufflers

The perfect choice for a variety of vehicle styles and engine applications, Flowmaster’s Laminar Flow mufflers utilize cutting-edge technology to provide maximum performance and deliver a sound quality like no other. The key to its superior performance and smooth refined tone is the Laminar Flow core design which delivers maximum exhaust efficiency, while at the same time minimizing the interior drone that is associated with other performance mufflers.

Laminar Flow Technology

1. Entry Cone
Exhaust is accelerated as it passed through the perforated cone into the outer core. The perforation pattern and entry angle are specifically engineered to provide optimum airflow. The sound energy is reflected and redirected back into itself as well as into the outer thermal core by the carefully selected taper angle of the entry cone.
2. Laminar Flow Area
Exhaust gases are released and allowed to expand into this section in multiple layers due to the tapered angle of the entry cone. This produces a controlled Laminar Flow pattern that reduces turbulence inside. Sound waves lose energy through the expansion of the exhaust gases and reflective angles of the cones, which direct the waves into the thermal barrier material.
3. Thermal Barrier
The barrier between the outer core and the case provides a portion of the muffler’s sound energy absorption. This barrier is engineered to deliver much lower exterior case temperatures, allowing the muffler to be placed closer to heat sensitive areas.
4. Exit Cone
Increased surface area and angle of the tapered exit provide an “easy exit” for the hot exhaust gases that encourages the flow out of the muffler. The carefully selected taper angle of the exit directs and focuses the sound energy back into itself. This convergence of sound waves reduces the sound level as it passes out of the muffler.

Cool shell technology is a patented internal design used in all Flowmaster Laminar Flow mufflers that dramatically reduces the exterior muffler temperature. This material also greatly reduces exterior heat making these mufflers great for chassis where exhaust systems must be mounted near fuel systems and close to the vehicle floor due to space limitations.
