About the exhaust tip

I had the tip of the tipless exhaust tip facing down and got such an exhaust tip still standing. But I want the type I want to be oval wide and on both sides. The one to be worn on the right does not need to have a real outlet, but I want it to be understood to be ornamental. How can I do it? Is there a need to cut the bumper? Or two ovals are attached to each side. How do I get the real exit?

I would like to say that the 206 sedan looks like a double exit to the vehicle. I would make the bumper grin without tearing it off, I would make it one by one .
