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.

POST 1 / ORIGINAL POSTEROriginal post

X post from te 996 GT3 forum as the parts are the same My Mk. I whent in today for fitting aftermarket stainless steel sport mufflers together with the OEM Tequipment tail pipes (large bore ones) and believe it or not but it wouldn't fit! The flange on the muffler and tailpipe don't match in size/diameter (outer edge) so the clamp is a few millimeters too big as the muffler flage is the smaller of the two. The angle on the flange also appear to be slightly different. Appreciate any ideas for a fix. Ciao, Johannes

I had the same problem on a set of Tubi exhausts I installed this Spring. With the OEM clamps, the exhuast flange was too small and the tip would not stay in place. What I did was create a "spacer" ring that went onto the exhaust flange, and then purchased the Fabspeed clamps (they get tighter/smaller than the OEM clamps). The spacer was just a piece of aluminum that was about 1/2" in width that I just wrapped around the edge of the flange - and then the clamp when on top of That fixed the problem and have stayed tight.....Hope this helps,Will
