Just because the A Body cars are tight does not mean it is the fault of the header mfr's, as you know. They produced a product they think will fit the majority of cars. Yeah, the el cheapo's likely do not fit as well. We know that. You are certainly welcome to your opinion as we all are, but not all headers are created equal either. Not all cars are configured the same just like all enthusiasts are not as skilled or as patient as others are either. Buying a cheap set of headers just to get a sense of fitment is not money well spent IMO. The cheapo's will not be the exact same as the higher quality ones, so what is the point? Install the set you want, make it work, and move on with life.
