Covered under the 6 year structural warranty.

If the catalyst loses its structural integrity due to a manufacturing defect, please contact us to see about a replacement. The inward deflection shown in the catalyst below is more than 1/4" and will no longer properly seal. This would qualify as a structural problem. Additionally, missing or broken pieces would qualify as a structural problem and is covered under the structural warranty.  Please note:  The 6 year structural warranty for a catalyst allows for a no charge one-time replacement. 


Not covered under the 6 year structural warranty.
A catalyst that is intact and has less than 1/4" of deflection will properly seal and is not covered under the 6 year structural warranty. If the catalyst is structurally sound but is not performing to your expectations you can take advantage of the 12 year 50% discount performance warranty.
