Big Gun Full System EVO U Exhaust Info:
With its deep and throaty tone, the EVO U series surely doesn’t disappoint. Designed specifically for utility ATV’s, sport utility ATV’s and Side x Sides, the EVO U series is not for the faint of heart when it comes to raw power and sound. If you are looking to dump your restrictive, tingy-sounding, stock exhaust for something that sounds nothing short of pure-MACHO, look no further.
Attitude GEN 3.5 Fuel Controller/Programmer Info:
- Plug N Play Settings Out of the Box for the setup
- Simple EFI Tuning Logic - Cruise, Acceleration, Full Throttle
- Push Button Interface for fine Tuning - NO Computer Necessary
