I called up a local muffler shop a-1 mufflers and asked them how much it would be to install a 3in cat-back and they said biggest they can do is 2.5in. I called another and they said I would need a new y-pipe.

They can adapt your 3" I-pipe to your Y pipe. There are little things called reducers. They are trying to get more money from you cause you didn't buy your system from them.

You can get a mandrel-bent one from dynomax. Get a couple of 90 degree bends from JCWhitney if you want to upgrade the S-pipe.
