Its not fake, dual exhaust is dual exhaust man. Only V8s use 2 mufflers. I have a big V6 and it only has one muffler, I wanted to do this, but dont have the money now... I might throw in a Flowmaster sometime though, or maybe a Glasspack...
I am starting to develop a custom flowmaster right now... exhaust is starting to rot out, lol, sounds a little louder, and I can hear some more airflow. Goes along well with the Cold Air.
