I have a set of old uncoated Hooker 2241 headers on my car. They fit perfect and absolutely love them. When I originally bought them money was tight and I bought uncoated ones. I would rather buy new ones than have these blasted and coated. This set has to be 20 yrs old and I am worried a new set won't fit as good as these. I'm sure they are cnc bent but I also know tooling wears out and there can be manufacturing differences especially over those many years. Has anyone bought a set and then replaced them years later that can verify fitment? Thanks in advance
