This exhaust system gives the RS turbo noise, depth, and sound. Stock, the RS sound is lacking. Since putting this system on my car, I have turned way more heads. I have seen people jump in their seats when the exhaust pops in sport mode. Being 21, I usually drive the car pedal to the floor, but sometimes I do just want to cruise. This exhaust is easily controlled with the throttle. If you want to just sound normal, just drive it like a normal car. There is no resonator or muffler, but there is no drone at all. For gas mileage, I average at 25 MPG, and I don't drive the car like Grandma and Grandpa. This exhaust system also eliminates a major design flaw in the stock exhaust system. There is a point just after the downpipe where the exhaust forms a bout a 1 1/2 inch triangle for packaging reasons and tool/hand clearance on Ford's side. MRT eliminated this feature for a more open and better flowing exhaust system. I would absolutely recommend this system.
