sorry about the confusion, what I am saying is GT spec aren't 95mm all the way, The piping of the GT-Spec cat back system is a very exclusive design. The exhaust starts with a diameter of 75 mm, which gradually increases to 95 mm where the pipe enters the rear mufler. The end pipe (output) is 115 mm!!!!
