Message: [QUOTE="TARM, post: 458326, member: 578"] Seth, I am like you have been holding off. For me really no other reason than the cost to perf benefit was rather low and others things were in front of it that were more worthwhile. I would say if you do not have water injection yet I would add that next as I think it will be a direct benefit to header longevity. From everything I have been told and seen the overwhelming reason for both cracks in the welds and warping seems to be high EGT related. 2K plus and the chances of issues goes up in fold. Keep things 1800 and under things look much better. Lower yet and even better. Do water and you have the tools to keep even a heavy fueled tune cooled down enough or at the very least lower than it would be thus increasing duty life of the headers. Just a thought anyways. The lower egts, more complete combustion, lower NOX emission, a small bump in power and fuel economy for water only injection and the increased life of other parts from the lower egts seems like worthwhile benefits for me. I was hoping to find a used set of headers but looks like I will end up having to go new. Might wait for a set from Steed if they will happen in the next few months. Maybe before or near the new year. [/QUOTE]
