If taken off the cougar, you need to know what comes with the setup..muffler, resonator...ect. Where the muffler was placed and all that jazz. Sometimes it will fit, other times it wont. Our rear is a lot small than the contours so certain mufflers that fit on a contour are too big for the cougar and vise versa. What does the piping do and where is the muffler, if included, and is it center in center out..or what.
include more detail please.
