I don't get why anyone thinks this is fraud. They haven't taken full payments, they aren't hounding us to get the rest of the money (the exact opposite in fact) and they're not going to ruin their business by trying to screw us over because they decided that at around 90% of the way done they just weren't going to ship them.
Bad business practices, yes. Communication with customers is key. To them we may just be another customer, but on an individual level, $750 or so for headers is a considerate purchase and we want to feel special and that the company we're ordering from cares about us. But outright fraud? I think some of you guys are just way to used to buying off the shelf parts and have never had to wait for custom made large orders to finish. Not to mention that some of these are external EGR, some are internal, some are for Ranger swaps, some designed to be used with 1" intake spacers, etc. And the fact that the last second gen Explorer is 12 years old. Our aftermarket is so limited, it's absolutely amazing these are still being made at all.
Basically, chill out and just accept that it's going to take a while. If you want to complain to them about it, then feel free. You have that right as a consumer. But don't be surprised if a lot of people don't sympathize with you.
