I guess its better to be walking beside your jeep having planned it then having a heart attack as your car drives away.
I haven't had any issues with my jeep's head after 80,000 miles operation (knock on wood).
I did however, destroy my Borla headers. I managed to crack almost all the welds on it after ~10,000 miles. I gave up sold the new one they sent me and put the original one back on. Its been fine for almost 70,000 miles.
I have considered driving the jeep around just to see what I could do mpg wise. Although, its kinda a brick. Not the best vehicle to start with when trying to conserve gas.
