Exhaust won't give a big increase in power, very minimal actuallyTires would be the number one upgrade, IMO. My confidence riding off camber trails went up ten fold after switching tires.
Since you already have an EFI tuner you could change the exhaust and get a big improvement in power. Noise is always a factor though. Depends on where you ride.
It does seem to change the power curve however... my Kodiak has a nice smooth curve now..Exhaust won't give a big increase in power, very minimal actually
