Our products are developed and produced in the North of Sweden where we have some harsh environment for testing. Long winters with a lot of snow as well as hot summers and muddy outbacks. The mufflers are built with the highest quality in mind, therefore we use thicker materials than our competitors to make sure our mufflers can withstand the abuse they are subjected to. RJWC stands for quality. We produce everything by hand in high-quality stainless steel and aircraft-grade aluminum. Our exhaust systems give you more power and a great overall look, but best of all, they last!
