What does a flex pipe do?
The flexible section reduces stress on exhaust joints as the engine rocks on its mounts. A failed flex section can leak even when the rest of the system looks sound.
Signs of a damaged flex pipe
Common signs include a louder exhaust near the engine, a rasping sound on acceleration and visible damage to the braided section. These symptoms can overlap with other leaks.
Can a flex pipe be welded?
A failed flexible portion usually needs a replacement flex section rather than welding the braid closed. Where surrounding pipe is solid, a new section may be welded into place.
What affects the cost?
Vehicle layout, access, pipe diameter, corrosion and whether adjoining flanges or catalytic-converter connections are damaged all affect the work.
When more than the flex pipe needs attention
A heavily rusted adjoining pipe or seized flange can change the scope of the repair. It is worth checking the complete joint before deciding.
