Common Problems This Muffler Can Address

Installation Notes and Tips
Verify the vehicle application before installation and confirm the inlet and outlet orientation match the existing exhaust layout. This muffler is not reversible and is not tunable, so correct positioning matters during installation. Clamps are not included, and the welded flange outlet should be matched to the vehicle’s exhaust connection points for proper sealing.
