Exhaust Pipe Replacement near Rockville, Maryland

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.

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.

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.

For bolt-on replacements, changing a section of the pipe is simple, especially if there is no oxygen sensor to change. That being said, if the pipe is to be manufactured for the vehicle, attaching flanges and installing the pipe will require pipe bending equipment and welding equipment. If this is the case, most DIYers will not have the tools or training to accomplish this task. On bolt-on applications, the exhaust bolts will likely be rusted, seized, and fragile, and heat or cutting may be required to remove the fasteners from the vehicle. If there is any doubt about removing the bolts, it may be best left to a professional.
