Ok I asked a few of the 2nd generation guys why the newer trucks sound muffled still even with a 5" straight pipe, and they told me they have heard of guys changing the manifold to a 2nd gen manifold and it makes it sound louder like the 2nd gen trucks, just wondered if anyone has done this to their truck. What all would you have to change to get it did?

 

I did a search with the terms "Exhaust" "Manifold" "Sound"
heres the top four threads each touches on the 2nd gen sound

Ok thank you for that, guess I should have tried to look it up before i posted huh? I just didn't know if anyone withthe 3rd gen trucks ever thought of this or just loved the sound of thier trucks. Thanks for the information.
