The silencer is underneath the metal plate under the airfilter box. There are some bolts that hold it on. I think they're in the bottom of the airfilter box.
I'm not sure if you have to take the passengers fender liner out or not.
First jack up the passenger side of the car.
remove front tire pull back the inner fender well there is three bolts holding the air box to the body remove them let the silencer drop down pull it out replace the three bolts.
