Leave it stock. The stock front bumper was engineered so well. Once you get into fake junk, you get nothing but problems. The only reason you would want to change out the stock front bumper is for more downforce, you can usually accomplish this by just adding a lip.

Plus if your doing it for show-appeal, the scene is changing. Just do something different. You can make your car unique with keeping it simple. I would say the most popular evos out there have the stock front bumper.
