    Exhaust shop i just went to said they highly advise against increasing catback tube to 3” cause with our engines you will lose torque. Based on that id stick with the factory size. He said mine was 2.5”. I went magnaflow. Also thats his opinions i have no idea if its accurate

    I would go 2 1/2" in and 2 1/2" out. That should work.
