I have a 4.6 and I want it to have a deep tone while idling. But want it to roar when I step on it. What do I get?

 

Cut the muffler of and just run a pipe out. I think you will like it I did it to my truck and it sounds great. I have a 5.4 so i dont know how a 4.6 will sound but if you don't like it then your only out a couple of bucks.
