Rear valance dual exhaust mod on a /6 car

Just wanted to know what most people were doing on their /6 cars to mount dual exhaust tips. Do you cutout the rear valance or replace it. Don't want it to look like a bucket of assholes. Once I start, I'm committed. Other side of coin, if I go with turndowns there is limited body work to fill cutout on drivers side for single exhaust exit. AMD has the rear valance with cutouts. Problem is I really want the exhaust tips. Rear of car is not so busy. Think they would look really good but I would be infringing on virgin car.
Not sure what year or model you're working on but you do mention a rear valance. If you're worried about infringing on a virgin car leave it alone but it sounds like you would really like to have an appearance of duel exhaust. Are you gonna sell it or are you gonna enjoy it. Don't worry about what others think or would do. Do what you like or wish .
Just my two cents .
