Lots of folks exit the sides in front of the rear tires (especially with fenderwell headers) Tends to be a little noiser for the driver/passenger than an exit behind the tires. More pipe and labor in an exit behind the tires, and pretty much need to go inside the frame rails to avoid issues with tires. Side exit will help with airflow sucking stuff back in from the rear.
