Header fitment rant, Doug's
I don't think the engines vary as much as chassis do. The #3 header tube should be pretty close to the oil pan, the second one I tried was the best fit bit still not as close as it should be.
My engine block and head can't be that far different than the rest.
On the last install you did, how close to the pan is the header, this is important to know. None of the headers I tried fit the same, none. That's not the cars fault.
The only conclusion I can come to is that the production standards are not very high, it has nothing to do with the car. Doug's did everything they could do to accommodate me, I do not fault the company for customer service.
