New Service Tailpipes Available for Silverado and Sierra

GM Customer Care and Aftersales has released new service tailpipes and clamps for exhaust repairs on 2019–2024 Silverado 1500 and Sierra 1500 models equipped with the 4.3L (RPO LV3) and 5.3L (RPO L82, L84) engines. (Fig. 1)

The replacement tailpipe is a cost-effective alternative to replacing the complete assembly when damage is isolated to only the tailpipe. Since rear collision damage may cause the complete exhaust system to move forward, resulting in damage upstream of the tailpipe, it’s important to perform a thorough inspection of the complete exhaust system prior to any repairs.

Exhaust tailpipe part numbers 85637485/6 and clamp part number 84612124 have been released to cover single- and dual-exhaust applications for the V6 and V8 engine applications (RPO LV3, L82, L84). (Fig. 2)

When installing the service tailpipe, position the clamp on the center of the joint to allow equal length of the inlet and outlet pipe to be inserted. (Fig. 3) Be sure to trim the tailpipe length as needed to adequately clear surrounding components before tightening the clamp to specification.
