I have a 2000 Super Duty with the 5.4 Liter. It is an extended cab, short box, in harvest gold. I would like to make her louder. It is my dads pickup so I wont have full say in the new exhaust. But I have heard the new f-150's and the Super Dutys and this is louder than any f-150s I have heard (stock). Do any of you have an exhaust that sounds powerful? He doesn't want it to Cackle when he lets off so glasspacks are out of the question. Just a nice deep tone. Thanks. Also dual exit and chrome tips are prefered.
