I have a 1985 Mustang GT that's been mildly modified. For exhaust, I've converted to true dual system with Ford Racing headers (heat riser connectors welded on), a BBK cat pipe and Flowmaster cat-back. In past testing I was able to pass with no issues. This time around, I knew there would be challenges to get by. The internal material in the cat pipe started breaking up and I had to fish it out because that loose stuff was rattling in there real loudly. Now it's rendered useless as far as scrubbing the exhaust.
With a cat pipe to replace, do I have to go back to single exhaust? If so, where do I find a replacement? So far I haven't been able to find an aftermarket replacement anywhere. Can I pass the visual inspection with a later exhaust setup?
I'm at a standstill. Any help would be appreciated.
