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.

13 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

I've got everything unbolted and the slip joint clamps loosened almost all the way off, but I cannot get the cat-to-header ends to unmate from one another; I've got about a 1" gap between teh cat flange and teh header flange, but that last 1/4" is standing in my way - not enough slack for the bolts to get out of the flange. Any tips? Thanks

POST 2Original post

First get the cat to muffler ends completely free... then yank. Watch your O2 sensor cables... the cats drop free and can damage the O2 cables.

POST 3 / ORIGINAL POSTEROriginal post

That was the ticket Paul. Thanks very much. I had the slide the slip joints to each side to make it happen. PB Baster is my friend. I am cat-free - at least for the moment. Those ***** are heavy

POST 4Original post

Do we need to do another "sans exhaust system" video?

POST 5 / ORIGINAL POSTEROriginal post

Ha. I just transferred the 02 sensors over, so no video from me.
