I need opinions from people who know what they are talking about. It is just the regular 4.6litre v8. It does have high performance catalytic converters on it and Straight pipes coming off those. No mufflers. Also a K&N Cold Air Intake. I am not trying to make it a speed demon just wondering what the best way to spend $1000 would be. I already know supercharging it would be best but not willing to do that.
