99-21 YZ250 FACTORY FATTY, FMF 024056 FRONT EXHAUST PIPE

• Other manufacturers have copied Gold Series pipes but nothing beats the original
• All Gold Series pipes are computer designed and dynotested to focus power gains where each machine needs it most
• Every pipe goes through the Tru-Flo stamping process to ensure quality performance and optimum fit
• Fatty pipe offers better bottom and top power
• Features the same shaped cone sections as the popular Fatty pipe, but offers some new features
• Raw, un-plated, oiled finish
• Header portion uses 19-gauge steel for optimum strength and durability, and body as well as the rear use thinner 20-gauge steel for increased weight savings
• Thinner steel yields 1/2 horsepower increase
• All seams are hand pounded after the stamping to give a smoother transition between sections for that factory appearance
