it's not like it's a drastic loss of power, and if he plans on going turbo it's better to go ahead and get 3in now so you don't have to pay for 2 exhaust systems.
Also it's best to buy an exhaust system that's mandrel bent so that the air flows smoothly. Most places just crush/crunch bend the pipes, which disturbs the airflow at the bends. I suppose if you found a local shop that could mandrel bend the pipes it would be cheaper than going with a brand name aftermakret cat-back. Good luck on finding one that does though, I hear they are pretty rare, and seem to be around here.
