Installation Notes and Tips

Confirm the vehicle’s exhaust layout before ordering, especially the single-outlet configuration and offset inlet/outlet dimensions. This muffler uses pipe connections and is not reversible or tunable, so orientation matters during installation. If the vehicle has a welded exhaust assembly, replace all required related parts to restore proper fit and sealing. Verify inlet and outlet diameter, body length, and overall length against the existing muffler before installation.
