The MAC headers I am considering for my 67 289 auto with A/C and PS are listed as long tubes and they sound to good to be true. Looking for anyone that has used them. Description below:
MAC 1 5/8" Long Tube Headers
Model number TF6466
"The only header for early Mustangs that doesn't require floor-notes, torches, or a power steering cylinder lower bracket for installation, and ground clearance is never a problem. Finally, an exhaust header that really fits!"
also:
"These long-tube headers are made from 16-gauge steel and are HTS coated to resist corrosion. They also include all air tube and sensor hook-ups for a hassle free installation. They include individual header flanges, and our collectors are a one-piece formed design to allow for precision fit to the H-pipe. MAC's True Fit Design eliminates gaskets at the collector (which eventually leak). These headers comes with threaded flanges, machined steel studs, and self-locking flange nuts."
