Big Gun EXO Full System Exhaust Honda CRF450R / CRF450RX / CRF450R-S

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
