I say YES a 3" pipe will be needed you can use a cat back from a 2g GS-T it will fit on your car. Also a bigger pipe will let you turbo spool faster and if you plan on re-building your motor and turning up the boost a 3" pipe will do perfect. If not a 2.5 will be fine, but always plan ahead for the furture and don't waste money.
