I am looking at adding side skirts to my mustang. My plan is to cut a hole in them and add a heat plate and run exhaust out of them. I know they make SVO sides but from what I hear they are hard to come by. I want to run it out the sides as this is a track car and I have no need to have mufflers or cats. So no reason to add extra weight with piping out the rear. I am thinking Cobra R front but unsure about rear bumper at this point. Thank you in advance for any advice!!!
