    5 of 5 Makes the RS sound like it should! July 18, 2017
    Reviewed by: Tyler Boes from Monroe, MI United States  
    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.
