Joe Gibbs Racing - FMF Factory 4.1 RCT Exhaust System with Megabomb Header

Yamaha YZ450F - Custom spec Team JGR exhaust, same race spec system used on the team race bikes of James Stewart and Davi Millsaps. Molded from FMF's Factory Ti 4.1 RCT exhaust, the team JGR exhaust features it's own internal spec differences that provide a broader power range from bottom to top for the serious racer, essentially putting power in the right places. If you are looking for a high end race performance exhaust that is custom built for your Yamaha 450's engine, look no further. 

Suzuki RM-Z450 - Custom spec Team BTOSports Suzuki exhaust, same race spec system used on the team race bikes of Michael Byrne, Matt Goerke, Jimmy Albertson and Jason Thomas.  Molded from FMF's Factory Ti 4.1 RCT exhaust, the team BTOSports Suzuki exhaust features it's own internal spec differences that provide a stronger bottom end hit and a smoother mid to top pull for the serious racer.  If you are looking for a high end race performance exhaust that will provide more of the 450 grunt that the stock RMZ450 lacks, this is your exhaust.
