TJ 2.5 exhaust manifold

So I am on my second exhaust manifold in about 30,000 miles. I purchased a after market exhaust manifold from advantage auto about 30k ago and now this one seems to be cracked. I am looking to see if anyone knows of a good aftermarket one. All i have found is a Banks for about $399.00 I am not lookin to spend that much. Any suggestions??????

Get an original factory two piece exhaust manifold off ebay. If you look hard enough you can find them for $150 or less shipped to your door.

I have a banks torque tube. It's expensive but built like a tank. I've had it on a couple of years and not a single problem. I really, really like it.

I had problems with the Dorman exhaust manifold cracking on my 99 with 250k on it...
I finally replaced the motor mounts and haven't had a problem since, it's only been ten thousand miles but I was cracking them every 2-3k

i went through 2 dorman manifolds on my 2.5 i was told that it was because of my motor mounts and i changed them when i put the 2nd one on. well, that one cracked also.if you put a straight edge against the edge you will see it is not a flush fit to the head. they were both like this and when you you torque it down during the heat cycles of the manifold it will crack at the points of the stress areas. i put a banks header on in may of 2012. well in feb 2014 it cracked were the 4 pipes meet at the collector. i called them 2 weeks back and sent them a copy of my reciept and some pictures. they were great about my trouble and with no hassle sent me another header and the welding looked better. i put it on yesterday and time will see
