The BBK Lt's are popular in my club,
www.midwestfords.org , mostly because they are inexpensive and have the single piece flange. If money is no object I think Bassani makes a set of step headers that are supposed to be very nice and I think Hooker makes a nice set too, but I never really looked into them because it's too $$$ for me. On the other hand I just bought a set of the chrome BBK LTs and have a leak on the driver side header that I can't seem to find. Had the same problem with the shorties I bought 3 years ago, ended up being a mnfr flaw, the flanges were tweaked. Not sure what the problem is now, but I've had problems with the quality of BBK in the past so I'm a little pissed off. Just a long way to say that you get what you pay for. I've heard nothing good about the Macs, eveyone I know that has them is going to the BBKs and hates the Macs.
