1. A. Flexible tubing may be used anywhere in the exhaust system.
2. B. Inspection of exhaust system does not concern noise level.

3. C. Inspect for and reject if:

   1. 1. There is any leakage of exhaust gases at any point in the system. Do not reject "built-in" drain holes in muffler or tailpipe.

   2. 2. A muffler or catalytic converter has been repaired in any manner. The exhaust pipe may be welded to the muffler or catalytic converter. Holes or cracks in the exhaust line have been repaired with a patch or caulking.

      NOTE: If a vehicle is inspected that does not have a muffler, the inspector should explain to the customer that although the vehicle will pass inspection without a muffler, it is a violation of state law for the vehicle to be operated on the highway without it.

      NOTE: Nissan has designed an exhaust repair for leak or noise at the front tube for the 2002-03 Nissan Pathfinders. The repair may require the application of a specially designed caulk to the front tube of the exhaust system. Since Nissan has designed the repair for their vehicles and trained Nissan technicians would perform the repair, this would be acceptable and should not be rejected. This exception would not preclude the rejection of exhaust systems repaired in a manner that is not designed or approved by the manufacturer and not performed by trained persons.

   3. 3. Tailpipe opening is mashed or pinched.
   4. 4. Any components of the exhaust system are not properly secured. Brackets or hangers are loose, broken, or missing.
   5. 5. The exhaust system fails to discharge the exhaust to the rear or sides of the passenger and trunk compartment of passenger vehicles unless such design is consistent with the original vehicle manufacturer exhaust system.
   6. 6. The exhaust system fails to discharge the exhaust to the rear or sides of the passenger compartment that is designed for and normally used for the driver and passengers of a property-carrying vehicle.

4. D. Trailers and semitrailer venting. Inspection of trailers and semitrailers will include a visual inspection of the venting of cooking or heating appliances to the outside of the trailer or semitrailer to determine if the heating and cooking appliances are adequately vented to the outside to prevent the asphyxiation of occupants of any trailer or semitrailer by the operation of the heating or cooking appliances.

   1. 1. Reject the trailer or semitrailer if not equipped with a vent or venting system to the outside.

   2. 2. Reject the trailer or semitrailer if there is any complete or partial obstruction of the vent or venting system.

      NOTE: Exhaust pipes must direct the fumes to exit from underneath of the vehicle to the sides or rear most area.

      NOTE: Exhaust pipes must extend behind the cab or rear axle of pickup trucks or utility trucks.
