Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Over the weekend, after 2 track days, I noticed a check engine light in my CS. I went to the dealer to diagnose the problem and I was subsequently told by their tuning division, Pfaff Tuning, that they need to remove, re-order and reinstall my fabspeed headers because the cats are defective. So I'm just wondering if anyone has had any issues with defective catalytic converters in their Fabspeed headers. Any insight into this situation would be greatly appreciated. Thanks in advance for your help. Regards, Matt

Can they swap them for Milltek headers?

POST 3Original post

Ken, Will the fabspeed catback mufflers work with the Milltek headers? If so I'll think about that option.

POST 4Original post

Yes they should all mount at the same point otherwise Fabspeed catback wouldn't work with stock exhaust manifolds and it does so yes that will work.

Matt, I had the same experience, but I haven't had a chance to get the problem checked as I am traveling this week. I'll let you next week if I have the same Fabspeed problem.
