A. Entry Cone

Hot exhaust gases entering the tapered inlet section are actually accelerated as they pass through the perforated cone into the outer core area. The perforation pattern and entry angle are specifially engineered into each product to provide optimum airflow characteristics.

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.

B. Laminar Flow Area

The hot 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 the muffler.

Sound waves lose energy in this section through the expansion of the exhaust gases and reflective angles of the cones which direct the waves into the thermal barrier material.

C. Thermal Barrier

The thermal barrier between the outer core section and muffler case provides a portion of the mufflers sound energy absorbtion characteristics. This thermal barrier is engineered to deliver much lower exterior case temperatures, allowing the muffer to be placed closer to heat sensitive areas

D. Exit Cone

The increased surface area and angle of the tapered exit cone provides an “easy exit” for the hot exhaust gases that encourages the flow out of the muffler. The carefully selected taper angle of the exit cone directs and focuses the sound energy back into iteself. This convergence of sound waves reduces the sound level as it passes out of the muffler.
