I dont have an SVT bumper on mine, but there are 3 Mystique owners on here (all post-98) that have it. From all the research i've done, It WON'T fit without custom fabrication such as molding it onto the exsisting stock bumper. There is a big difference in hood, grill, and headlight shape compared to the contour. So basically, no basic bolting on and look to spend at least $1000 to have an SVT bumper on your Mystique.
