They only have a 2.5" catback(a.ka. whole system with 1 part number) for thirdgens but if you get all the part numbers and give them to him, you can still do the old 3" catback. I have the partnumbers for the I pipe. Call dynomax for the 3" in, dual 2.5" out muffler with matching tailpipes. It bolts to stock cat so don't wprry about that.
