Your best bet is to use this picture and go to your local auto part store and try to match up the pieces. As for taking out the silencer there is a few decent how to articles even though the pics dont work should be easy to figure out. I know on Spectres site they also have a section of pipe for the MAF sensor. I personally havent done this but I am in the same boat and plan on doing this same thing when I get home. So if you do it make a how to thread so in the future people can use it.
