These are probably the nicest headers I've ever bought. The finish is extremely nice and the flanges and smoothed and polished. The tubing is very thick so they should last literally forever. Hardware is also top quality. An awesome quality investment.

Nice looking. Thick flanges. Seems like great quality. I had Hooker headers on my previous Mustang years back. Had a lot of problems with the bottom of the headers bottoming out on speed bumps because they were so long, low. The flanges were thin as well so had a lot of exhaust leak problems. These don’t seem to be as long. I’m excited to get these installed in my 72 mustang.
