Removing the baffles will:
1. Make the exhaust note much louder and allow additional polluted exhaust gases out.
That will most likely result in DOT (Noise) and EPA (Pollution) violations. Depending on where you live that means traffic tickets.
2. Reduced back pressure.
This will reduce your "low-end" torque but will increase your "high-end" torque. This is why racing engines are always run without baffles. To racers, top speed is more important than how fast they're off the line.
3. Engine will run cooler.
Since the exhaust gases flow without restriction the engine can shed heat more efficiently. That's a bonus on the air cooled V-Twin Harley motors.
If you have O2 sensors then the ECM will most likely automatically recalibrate to accommodate the baffle removal, but if you also have a high performance (high flow) air cleaner, you should get an aftermarket tuner to do the recalibrations.
