2006 4.0 Auto with 32’s and 2.5 lift
Ok so I installed the Eastern Cats but still waiting on my exhaust.
First off the cats seem to be made of good material except the flanges : brace they’re made of a softer metal. I tried to torque them down to specs but could not get to even 20ft lbs without probably damaging something and it’s extremely tight in that area making it even more difficult. The bolt started biting into the flange eyelid see pics, but I did manage to tighten them as much as I could they feel solid.
Tubing goes nicely around oil pan.
O2 sensors ports are well placed no issues. Flanges seem to make a good seal at the manifold.
Cats come in two sections upper two and bottom third.
In order to avoid drop tube being to close to shaft it has to be closer to the oil pan making the cat heat shield touch lines above. We’ll see if they still don’t hit shaft once I drive it.
Seems to be an issue for some
I didn’t need to drop front shaft nor skid plate to install.
Suggestions
Buy new bolts and inserts
And buy a band not a clamp just Incase you need to remove it later.
My cats didn’t come with any clamps.
Over all I am pleased
