What I think of the BBK Crossovers installed in my 1985 TBird.
They arrived in a large box, but the packing allowed them to bounce and bump against the other pipes in the box. The quality was very good and welds were professional. The fit is actually remarkable and surprisingly they fit my 1985 Ford Thunderbird perfectly. Installation requires cutting of the pipes to fit this car. They have made the pipes long, so I had to cut 2.5 inches off the front X pipe and cut the rear pipes evenly since I am not using any catalyst.
