T-PHLO Mufflers. These high performance mufflers are really impressive. I gained about 15 hp on my truck. The sound is incredible! My family has always gone the way of "name brand mufflers," but this new one is mean, tough, and all around better than the rest. All my friends are getting them on their vehicles and say the same thing. I would say if you do not have a T-PHLO then your car sounds like all the rest.
