Hello, I recently purchased a 2019 Fiesta ST with around 75k miles. It has a Magnaflow catback exhaust on it currently. It sounds decent up to around 55 MPH but then begins to drone. I like an exhaust that pops and gurbles but not a fan of the drone. Is there a means to improve the Magnaflow or is it best to entirely replace it with the Thermal R & D exhaust? If best to replace, is there a recommended merchant? I may need to bite the bullet but wanted to see if there was any other proven option vs replacement. Please let me know and thank you. The dealer also included the K and N cold air intake they removed from the car. I will likely reinstall it at some point.
