I tried using the VMF search feature but found everything else, but no reference to this exhaust system. I just purchased one for my 67, and wanted to know if anyone installed one on their 67. If so were there an installation problems? The system is listed as for the 65 thru 66 Mustangs, except for the GT's due to the GT rear valance. I remember someone on the Forum mentioned using this system on their 67 with no problems.
