Hello all, I found something interesting. An ad for Walker mufflers on the back of the January 1979 Napa "Parts Pups" magazine. It has a photo of the original DeLorean prototype. Since this publication was only for Napa employees, Im sure any remaining copies of this are rare. My father got it when it was new when he worked for Tenneco automotive. One of the lines is "We make it sound as good as it looks." I just thought this find is intresting Andrew 4194
