    I would leave em. High flow cats are a waste of money cause the stock ones flow pretty well actually. Putting an off road y pipe on (no cats) will make your car a lil louder and maybe pick up a few horses but for the money you'd be better off getting a header/off road Y combo and pick up 20 hp.

    Couldn't fit high flows in my car at all, no room period. Stocks won't fit either. So I went no cats
