I was lucky enough to find a set of new pro parts headers in the box for my car. I know some people dont want to cut the inner fenders but I have no interest in the tti big block A-body headers after hearing so many complain of fit issues. I know when you are dealing with conversion mounts, D.C. k-frame, motor plates there are too many variables to get all those tubes inside the chassis so I don't blame tti. I am sure they do their best but I am not paying big money for a product that may or may not fit.
