You have to measure real good and take a recip saw with a new blade and cut two square holes in the rear bumper.I put black electrical tape around edges to make the cut look professional. It also makes the exhaust ports fit better. A friend said you can use a blow torch to re route the exhaust into the new ports. I am not going to use a torch on my exhaust, im scared of the gas tank. Taking the car to a muffler shop and let them take care of this. I don't think you will be able to tell this from factory , hope not. Bumperking

 

pictures will determine if you are indeed the bumper king.
