My 2020 ST has been a gem of a car, no issues through the first 90k miles. The other day while driving, the engine noise suddenly increased, not wildly but noticeably. Seemed obvious that some sort of break/crack/leak had occurred in the exhaust system. I took it to the Ford dealer closest to where I am living and they are quoting me $4,995 to repair. Claiming they have no choice but to replace the entire exhaust system as it is all welded together, even though it is just a "cut" in the muffler. This seems to be $3,500+ higher than everything I have researched online, even for complete exhaust system repair. I am not a mechanic myself, but I am also not a complete rookie when it comes to this stuff after years operating and working with equipment. It seems like something that should be easily weldable or if not, at least replace just the muffler etc... Does anyone have any suggestions or thoughts on what my best way to proceed is? I appreciate any honest advice that can be sent my way, thank you!
