Doing this mod with your setup will more than likely just make it louder and introduce "crackling" and backfiring with an aggressive fuel pedal.
I wouldn't expect too much power wise, but throttle response should be a tad quicker. I had a similar setup on a 95 and liked the aggressiveness, but the crackling when the engine was cold was a bit annoying. I now prefer smoother deeper tones, But some guys still like that stock car sound.
Just make sure you like LOUD & cranky!
