I have a 72 Satellite, 440, AT 727 floor shift, Pwr Steering and Pwr brakes, mild performance build, but now need to swap out the stock HP exhaust manifolds for some headers. I was told by a smart friend to go with 1.75 tubes. Personally, I've always like Hookers but want to make sure they fit without too many issues. I looked at both the Hooker Competition and Super Comps and can't figure out the differences between the two as far as fit and performance. Someone else mentioned block huggers, but I don't see any models that are described like that. I guess I'd like to know if anyone has any experience with headers and the 72 body style. Thanks in advance for your help!!!
