RJWCstands for quality. Everything is Produced by hand in the highest quality stainless. Our mufflers are made of thicker material than our competitors to withstand the abuse they are subjected to. The choice of wool in our mufflers is a ceramic mat/plate that can withstand over 1200 degrees Celsius (2000 Fahrenheit), we now use a completely new type of pillow also that surrounds the ceramic mat to keep down the temperature of the outer shell of the muffler low.
