Exactly. My '97 TJ is on its 4th header but the last one the dealer installed just before the warranty expired was the newer crack resistant style and it has held up just over 100K miles now. The first three older design headers cracked within 36,000 miles.1BLKJP said:First we should figure out why the ones you are replacing have cracked so often. What have you been putting on there? Because the newer version of the exhaust manifold from 2000 on up haven't had the problems that the 91-99 4.0 manifolds had.
Nope, the rest of the exhaust wouldn't cause this problem. You've had three from Autozone fail, I'd think that is a huge clue that Autozone's design is bad even though it has the flex joints. My redesigned factory header, as I said above, has held up fine for 100K miles now. Three of the older design headers failed on my TJ within 36K miles. Banks reputation on TJ headers isn't so good either so I would also avoid that brand.cueball said:Maybe a whole new exhaust system is the answer
Try a few dealers and NEGOTIATE with them, you'd be amazed at the wide range of prices different dealers will quote for the exact same part.cueball said:THANK'S I'll give that a try
I get them from the dealer dont i ?????????
