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.

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

POST 1 / ORIGINAL POSTEROriginal post

I found a good set of sport mufflers from a 997 and was wondering if they will fit on a 996 ???

POST 4Original post

I think if it's the 997.1 they fit but the later cars went With the DAI engine and I'm pretty sure they are different, hopefully others will chime in, part numbers and make will help

POST 6Original post

Do you have an image of the other side? The inlet and outlet look very similar to the 996 but mm could make the difference. Also some tuners actually change the exhaust internals based on the model. Cargraphic (my exhaust) I know do this.

unfortunately I don�t

POST 8Original post

I'd also like to know about this. My mechanic (a long-time Porsche mechanic) has a 997S sports exhaust and he said it would fit my 996.1 C4. I'd like to do this later in the year, but haven't researched it yet.

Thank you.

POST 11Original post

Phil From Fabspeed here. No, the 997 mufflers have outlets that come all the way down to the bumper cutout versus the 996 which come down behind the bumper and the tips themselves have longer inlets on them to connect the mufflers outlets. We have a fantastic set-up for your 997 at a great price. Our maxflo would add a little more sound and are much more free flowing.

POST 12Original post

That Fabspeed stuff sure looks nice but I am not sure it’s very practical from a cost standpoint. I know for me getting the fister mod and having my mufflers cermachromed all for under $1000? It’s crazy to do anything else.

This is a source reference. Confirm exact model applicability in the original material.
