4.6 True Dual?
I have a 97 F150 with the 4.6 and true duel exhaust. It's a custom exhaust system done by a local exhaust shop, they did a great job. It uses 2 2.5 inch pipes (original factory daimeter) with 12inch glasspacks in each pipe going out into 3.5inch diameter tips. I really like the sound and I noticed a slight increase in power throughout the whole RPM range.
If your going with true duels make sure you keep your cats on and put glasspacks in order to have the most power and fuel economy without sacrificing much in sound. The newer engines need to keep backpressure because thats where they get their power from.
