We could go on for days about this badass dirtbike exhaust but we'll keep it short and sweet. FMF® achieves a shorter overall length which lessens the chance for crash damage. They also moved the muffler closer to the motor to centralize the overall mass of the bike. The Factory 4.1 RCT Full Exhaust System is constructed from aerospace-grade materials that meet their exacting specs. As you all know, space materials are the best materials. Oh, and did we mention that all of their products are 100% manufactured at their Rancho Dominguez, California factory?
