        Roush Phase 3 kit

        I was looking to increase my torque without installing long tube headers and figured this kit would be a nice start. As always, AM did an outstanding job in getting the kit to me; service was great! After installation, I had it on the dyno rack; 581 HP, 511 TQ. This was an increase of 21 HP and 67 TQ. The increase in torque is great and it seems that the gas mileage has improved a bit as well.
