Muffler Guide: Dirt

Building performance exhaust systems for the factory race efforts improves our research and development, which improves the overall performance of our products. Adapting technology we learn on the track to our consumer products is what makes the Yoshimura name synonymous with quality and performance. One look at our RS-9 and RS-4 exhaust systems illustrates the endless cycle of development. Working in conjunction with the factory teams has provided us with new ways to increase performance, lower sound levels and centralize mass. The end result is a product that gives you an unparalleled competitive advantage.

At Yoshimura, we make replacement parts available for those times when some repairs are in order. Just call one of our Sales Techs with what you need. Sales Department: 1-800-634-9166.
