The L&L headers come in three varieties. Your choices are the full-length, fenderwell-exit model mentioned earlier (79750A), a full-length, chassis-exit set (79750G), and a new shorty header (79750H). We went with the shorties to keep maximum ground clearance. All are formed from 14-gauge tubing, have oversized port openings, use 1/2-inch (yes, 1/2-inch) thick port flanges, and are all covered in a electroless nickel plating that allows for a lifetime warranty against rust. Heavy-duty!
