Big Gun EXO R Full System Exhaust
The EXO R Series was developed to meet the growing demands of larger, more powerful MX engines, requiring a more robust muffler. Designed from the ground up, it features a unique hexagonal aluminum body and a coned stainless steel inlet, allowing for increased volume. This design produces a deeper, more aggressive exhaust note, while effectively reducing 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 header and mid pipe
- Carbon fiber end cap
- Significant horsepower and torque gains
- Removable screen-type spark arrestor included
- Handmade in the USA
