Do you need power commander after exhaust change?
So, to recap, adding a power commander after doing a full-system exhaust change isn’t “necessary” in the sense that your bike won’t run afterwards. It is, however, advisable if you want to maximize the power gains from changing the bike exhaust.
Do you need a Dynojet power commander with a full exhaust?
Let’s take air/fuel management systems — like the Dynojet PowerCommander — as one example. Most can agree on what it’s for (fuel control). Most can also agree the PC is good at what it does. Fewer, however, agree on what situations call for its use the most. Do you need to have one with an aftermarket exhaust, for instance?
Do you need to change the exhaust on a Harley?
I have been led to believe that the modern H-D’s will adjust the air/fuel mix depending upon the O2 sensors so you don’t need to re-map a simple exhaust change. As said above, it won’t be optimal so re-mapping will always help.
How does a fuel controller work on a power commander?
Fuel controllers use computer generated settings (maps) to change the amount of fuel delivered to the engine. In the case of the Power Commander, users have access to a large database of maps. Riders can download these maps from Dynojet (the PC’s manufacturers), then apply the settings to their bike to tune their air-fuel ratio.

Can you change the exhaust on a bike?
There’s no shortage of anecdotes from riders who have switched up the exhaust, skipped out on the PC, and had their bike not explode right away. That’s not true in every case, though.
