Thank you everyone who recommended dual cat back with no mufflers. I had mine installed at midas yesterday and still cant get the grin off my face. This is the only way to go with the 4.6. I havnt noticed any lose of low end power, but if I did, Trust me it was well worth it!
Thanks Again

Good for you amigo, how loud is it? Are women and children pulled off the street as you cruise by? Any resonance in the cab? Inquiring minds gots to know!

The noise in the cab at cruising speed is not bad at all, I can talk on my cell no problem (not that I do though).Honestly the only time you really hear it in the cab is on excelleration, even then its not bad, perfect for me. I had my wife drive it while I was behind her and the tone is SWEET!! Not loud enough to get cops attention(UNless you stand on it). While cruising, I really couldnt hear it from behind. I recommend it to everyone with the 4.6

 

Best sounding after flows, dynomax and a glasspack I decided on straight pipes best thing I ever did.
