b. Any joint is loose or leaking, including manifolds. Does not include minor leakage at exhaust control valve (manifold damper or heat riser valve).
c. Manifold is cracked or broken causing leakage.
d. Holes, leaking seams, or patches on the muffler, resonators, exhaust pipe, tailpipe, or catalytic converter.
e. Exhaust system is not secured to the vehicle by mounting brackets designed for exhaust systems (wire is not acceptable).
f. Any brackets are loose, broken, or missing.
g. There is excessive vibration of exhaust line.
h. Any part of the exhaust system passes through the passenger compartment.
i. The tailpipe is broken, pinched, or eroded off to the extent to allow exhaust fumes to penetrate into the interior of the passenger compartment.
j. The tailpipe fails to discharge exhaust from the rear or sides or top of the passenger compartment of the vehicle.
NOTE: Holes in the exhaust system made by the manufacturer for drainage are not cause for rejection. The tailpipe must direct the exhaust fumes out from under the passenger compartment.
b. The exhaust emission system has been disconnected.
c. The plumbing or hoses are loose, broken, leaking, or improperly routed.
d. Air pump (air injection-type) belt is loose, removed, excessively cracked, frayed or has pieces missing.

3. Gas Cap Testing. Every gasoline-powered vehicle* from 2-24 model years old will be checked for presence of and by a Department approved "Gas Cap Testing Device" to determine if the gas cap is missing or defective. The following vehicles are exempt:
a. Antique vehicles.
b. Slow-moving vehicles.
c. Motorcycles.
d. Vehicles operated exclusively by a fuel other than gasoline.
e. Vehicles newer than 2 years old and older than 24 years old.
4. Inspection Procedure.
a. Conduct daily calibration check of gas cap testing device.
b. Check for presence (all gas caps must be checked).
c. Check for correct type of gas cap(s).
d. Remove gas cap(s) and test using an approved testing device. (Gas cap present but not testable will not be cause for rejection.)
e. Any gas cap(s) failing the initial test will be tested a second time to verify failure.
5. Inspect for and reject if:
a. Vehicle not equipped with required gas cap(s).
b. Vehicle not equipped with proper type gas cap(s).
c. Gas cap(s) fails both tests.
NOTE: When a vehicle is presented for inspection and the vehicle is from a designated emissions county and is subject to the Texas Vehicle Emissions Inspection and Maintenance Program an Affidavit (VIE-12) is required. (See Chapter 5, page 5-14.)
