Which Exhaust Manifolds?

If your using a 6.1 motor you will need the 2009 or newer 5.7 LX or Jeep manifolds so they will match the ports on the 6.1 head. IF your using a 5.7 you can use the 2008 and older lx or jeep manifolds. I have used the jeep manifolds on B and e body's but never on a A body. The should fit no problem. I just like the looks of the LX manifolds. Here are a feew pics of the frame modifications and a pic of all 4 manifolds. Top is SRT next is the LX next is the Jeep and ram on the bottom. The other good thing is the LX has the spot for the o2 sensor.
