Installation Notes
Verify the inlet offset and outlet center configuration before installation, since this muffler is not reversible or tunable. Confirm the vehicle build date for 2000 Ford Explorer and 1999-2000 Mercury Mountaineer applications, as the fitment notes specify after 12/1999. If the exhaust system uses a welded assembly, replace all required related parts during service to maintain proper alignment and sealing.
