Yup this one is mostly looks, could be for sound too, but it's relatively easy and can be inexpensive if you're lucky using OE parts or aftermarket. The lower valance is simply a r&r with a new part for $80-$200 depending.
You could also just tag off the right side for ease and cut a hole but OE being so easy it's nice.
There's plenty on this to make it paint by numbers. I like the look, I'd add the 4" tips at the same time.
