    a bolt in pipe WITH CAT will come with a high flow cat.

    you may or may not throw the P0420, you wont know until you run it.

    t stat will do no good, your fans arent set to come on at 180*... need a tune to benefit 180 t stat..... that comes further down the line into modding.

    how far are you looking to take the car? you should consider headers you can get them for almost as cheap as the dp with a powerlog to replace your front manifold( which is another restrictive area in the factory exhaust setup).
