Installation Notes and Tips

Verify Federal Emission System coverage before ordering, and confirm whether the vehicle is equipped with the High Rider option or package where noted. Match the inlet and outlet flange style to the original exhaust layout, and inspect adjoining gaskets, fasteners, and hangers during installation. Because this is a specific-fit exhaust component, proper alignment with the existing exhaust system is important for sealing and clearance.
