Just got off the phone with my inspector about a set of longtube headers, I'm pretty sure im gonna order a pair of mac LTs later this week. He said as long as my O2 sensors were there itd be fine for state inspection and emissions. Which made me happy because I'd rather go with LTs over shorties.

My question to you guys is if the mac LTs flange insert for the 4.0 will fit into the flange right before my cat? I know the cat will need to be moved and some piping will need to be chopped and re welded so the LTs fit and understand that completely. I just need to know if the header flange will fit up with the front cat flange once I move the cat. If it will then Im all set, if not I may have a little more work ahead of me. Let me know what you guys think.

If you're keeping your cats then they will need to be custom fitted....i'm pretty certain the flanges won't match up unfortunately
