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.

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

      "Out of all our exhaust testing, the FMF Factory 4.1 RCT exhaust was the best standard exhaust we tested with on the dyno. JGR and FMF then went the extra mile through 3 months of motor testing to get the exhaust even that much more precise to pull the extra HP our team riders needed out of our RMZ450 race bikes. The end result gave us the stronger bottom end hit our riders were looking for out of the Suzuki, but also allowed the bike to rev that extra bit to compete with the top factory race bikes in the world. Our riders starts have proven the exhaust this SX season, with several heat race holeshots against the best in the world. The JGR / FMF 4.1 race system is our BBMX Suzuki RMZ450 factory race bike spec exhaust, and if you are looking for the best performance gains out of your race bike (along with that sick factory look), then this is your exhaust" - Forrest Butler, BBMX team owner/manager
