Just bought my f-250 a couple months back. I got it running with some help from friends. Just this past week, it got an entire new exhaust from the manifolds back. Now, I've discovered I've got a cracked manifold. My question is, where is a good place to buy manifolds from? LMC has them for $100 bucks apiece. Are $100 manifolds going to be good or not. And no, I don't want to put headers on.
