The other fix was to put headers on,not an option here in California due to smog regulations.
There are approved headers and other aftermarket performance parts available that do meet the Cali requirements.

At the time mine failed there were no California approved replacement parts,believe me I checked.
As others have said check your warranty,that is how mine were replaced for free.
Banks has had CARB approved replacement exhaust components since the early 90s.
