Getting ready to install the Mopar Headers on my 06 QC next month. I have notice several different items that have cropped up with other installs and have made a few notes to check during my install to eliminate future problems. This is directed more to the Mopar Headers and Mids but I suspect would apply to almost any of the Header Brands.
Virginia requires Cats for State Inspection so I am going with High Flow Cats Installed into the Mids. The Mopar Mids already have the Bungs for O2 sensors and also a bung for the A/F (If I put one in). I know some have tied the O2s up but since I have the bungs already there I will be installing them.
Some things I have noticed are:
Make sure they are coated (The ones I am getting already are)
If the Headers are Coated DON'T Wrap them (holds too much heat in and will burn the coating off)
1. Sounds right but is this true?
Damaged O2 Sensors or Crushed Wires causing error codes;
O2 Wires too close to the headers and burn through or are damaged;
1. Should they be heat wrapped?
2. How far away from the headers do the wires need to be?
3. Where do I get and what brand of O2 extensions for the QC?
Only use the Factory OEM Gaskets
Wrap items close to the Headers
1. Which items/parts do I need to wrap to prevent damage?
Some have trimmed Fenders back up to 3 inches
1. Is this necessary or simply a safety zone?
Cut the Mids for Cat Install and Clamp (Do not weld in, burns the coating off)
1. Where is the best location for them to be cut in?
2. Closer to the Collector or further back?
Pull the Fender Wheel Liners during install to get better access
Some have changed bolts out
1. Should I change the bolts out with new?
2. If so should it be OEM bolts or SS?
Make sure the Header Heat Shield is put back in place.
Like I said these are some of the things I have read and stuck in my head. If there is anything else I need to be concerned about Please Chime-In and let me know. I don't want to go back in and fix something that I could have prevented by some proper planning and proper install procedures. (Proper Prior Planning Prevents Piss Poor Performance)
