MRD and twin air

GYTR tuner is the oem tuner and works well for most

If you want more precise control over fuel system you'll need a power commander 5

I think the gytr will be fine for the riding I will do, also the fmf 4.1 slip on seems to be a good choice, along with the twin air filter.

Gonna try the fmf and twin air first then if I need the gytr tuner I'll get it.

Also what about the pro circuit t-4 slip on, I like the thing that they give you a repacking kit and I think a silencer and spark arrestor too.
