Yea as Gus said I use a full TTI 3" system. The tailpipes fit great as I installed the full system in my driveway with the car just jacked up about a foot at the most. It fits great and was easy to install on my 63. I do use 3" tailpipes but I have heard that the exh gasses have contracted enough by the time they hit the tailpipe that 2-1/2" tailpipes work fine on a 3" system. Ron
