Yes it's possible but not recommended on a car with such small engine and without turbo. You won't most probably get any power increase. It will change the sound though, but normally people do install custom mufflers if they only want to have better sound.

Someone on this forum have stated that on a 1.6 engine it'd be possible to reach almost 10hp more after the upgrade, but as far as I know the car wasn't taken to a dyno test so all that is just hearsay. Don't remember who's the owner, but correct me if I'm wrong!
