Big Gun EXO Full System Exhaust Yamaha YZ450F / YZ450FX 

EXO Series came about from a realization of the need for a bigger and better muffler that could handle the huge demands of the larger, more powerful MX motors. The EXO Series is the ground-up approach at just that. A unique hexagon shaped aluminum muffler and stainless steel coned inlet allow for significantly more volume, delivering a louder but tolerable deep sound while also decreasing heat.

Features:

  • Light weight brushed aluminum muffler
  • Hexagon shaped large diameter housing for more volume
  • Internal sound wave altering technology for a deeper but tolerable exhaust tone
  • Stamped 304 stainless steel coned inlet for more volume
  • TIG welded reinforced muffler bracket(s)
  • 304 stainless steel mid pipe
  • Black powder coated stainless steel end tip
  • Significant horsepower and torque gains
  • Removable screen-type spark arrestor included
  • Handmade in the USA
