• Removing the baffles will change the backpressure. Whether it will be enough to hurt the engine is something you need a meter to measure.

• As long as he gets the EFI correctly remapped (or rejet if the bike is carbed), it won't hurt the engine, but it will seriously hurt performance. I definitely wouldn't recommend it unless noise is all he cares about.
  
  There are several aftermarket exhausts, both slip-on and full, that will be louder than SE without hurting performance. I would say go with one of those or risk looking like a noob poser.

• To be more specific, removing the baffles can cause issues with both reversion and backpressure, which will give you a major drop in the powerband right at the rpms you use most.
  
  You only need to worry about engine damage if the fuel mixture is too lean , but it will be unless you remap or rejet.
