I recently had these old Mac Equal Length Shorty Headers on my motor and developed an exhaust leak so I pulled the one off to find that the 2 of the tubes are totally warped and wont re-bolt up unless I bend them back into position. They do not have the cross flange metal brace between the exhaust tubes like every other manufacturer out there selling headers (Dougs, Flowmaster, ect) so I am canning them. I have the whole top half of the motor apart and was wondering if I could even just go with some long tube headers since now is the time to do it. Can you even get long tubes in the car without pulling the motor or whats the deal with the installation on them? Second what brands do you guys suggest and have had good experience with? Thanks for any help.
