I have a problem when the engine gave off a loud noise when running. The sound seems to come from the engine, not under the car or muffler. The mechanic diagnosed it as a cracked flex pipe that runs to the exhaust. Apparently, in some cars, the engine literally lifts on its mounts when the gas pedal is pressed. This strains the connection to the flex pipe, which sometimes cracks/breaks. Now the exhaust escaping from here, gives off the loud noise.
Cost to replace the flex pipe piece $175. He also suggests that I replace the engine mounts to prevent it from lifting when given gas. Cost for this $275.
I will get the pipe replaced, but should I also replace the mounts? If I don't any idea how long the flex pipe will survive before it breaks again? Any info will help. Thanks
