Straight Pipes
Straight Pipes
2003 4.7L Durango w/ California emissions
I wanted to know if I can run pipes from the downstream o2 sensor straight to the back of the truck and still be ok with emissions, sensors, and air flow? Im going to buy two new Magnaflo Mufflers for the ends.

I made this post a while ago and just finally got around to get the new pipes put on.
So, come to find out I have a 3rd Cat. After the downstream sensor, the pipes go into one and go into another cat, then muffler, then out the back. So to keep it street legal, I cannot have straight pipes. Also, they showed me it would be a difficult job due to the spare tire and my tow hitch. They suggested I would remove those to get the second pipe. So, I think I am going to go with the MagnaFlow's Glass Pack 26", but I have no idea what it will sound like on my 4.7 If it doesnt sound great, Ill have to find something else. Just wanted to leave an update.
