Exhaust Pipe Replacement
How are Exhaust Pipe issues diagnosed?
Diagnosing a leaking or perforated exhaust pipe simply involves looking for the leak, or following the sound. Exhaust pulses from a leaky exhaust pipe are unmistakeable to the trained ear, and are sure to be the loudest thing under the vehicle. Listening for a leak, and focusing on the rusted or corroded portions of the exhaust pipe will soon yield the discovery of the leak.
How are Exhaust Pipes replaced?
Since exhaust pipes are either clamped together or welded on, the replacement procedure may be to cut off the portion of the pipe needed replacement, or disconnect the portion of pipe at the clamping location. Once the bad section of exhaust pipe is removed, the new section can be cut to size, fitted, and clamped or welded in place. If the portion of the exhaust has been ordered from the manufacturer, only removing and replacing the fasteners is typical, but if the pipe is being repaired from raw pipe, the technician will likely need to bend the pipe to match the old section before refitting and welding or fastening the pipe in place.
RepairPal Recommendations for Exhaust Pipe issues
If one portion of the exhaust pipe is perforated due to corrosion, it is likely that another location will soon have the same issue. having the entire exhaust system inspected for corrosion and damage can prevent a return trip to the shop in the near future. Also, the rubber and metal brackets used to secure the exhaust to the vehicle should be inspected, as the exhaust system is fairly heavy and will encourage corrosion to create perforations if not secured properly.
What to look out for when dealing with Exhaust Pipe issues
While repairing the exhaust pipe, it is extremely important not to bump or misshape the heat shields surrounding the exhaust system. Changing the position of the heat shields will nearly always cause the heat shields to vibrate at certain engine speeds due to engine vibration frequencies at those speeds. There are many sizes of exhaust pipe, and ensuring that the inside diameter of the exhaust pipe matches the replacement section will help avoid issues during installation. Always measure the pipe before purchasing a replacement section.
