Hello FellowRiders,

I need some advice on whether it is recommended or necessary to get a fuel commander, if I have an aftermarket slip-on exhaust?? To be specific, I have the Two Bros V.A.L.E.™ Black Series M-2 Carbon Fiber Canister. Thanks!

Ride Safe,
Armando

I come from the car tuning world, and in that world it is my experience that any simple exhaust change won't affect the A/F ratios nearly enough to require a fuel delivery change. Maybe if you had a full exhaust with no cats...

Not necessary. A stock bike runs slightly rich, and a slip on will lean it out a bit. If you have a slip-on and aftermarket air filter, it is worth considering.

It's not required and won't improve drive ability much
