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.

POST 1 / ORIGINAL POSTEROriginal post

I have this stainless system fitted to my 996 3.4 C2 and I want to do a gundo hack. My questions are what boxes are these and what diameter pipe to use for a good improvement in noise without drone on my tiptronic car? Any advice very gratefully received. :thumbs: [/quote]

POST 2Original post

I initially thought they were Dansk boxes , they look very similar on the brackets .. but Dansk tend to have a flexi pipe in them so im not sure now . Perhaps Topgear . I often see the gundo hack and the pipe is about 4 cms across on all models . Droneing is indeed a problem though .. some customers have hated it .. on a Cayman you can put sound deadening in the boot to stop it . 996 .. well theres plenty of places to put it on the inside at the rear to quieten it down if needed .

POST 3 / ORIGINAL POSTEROriginal post

Thanks Iain.I think I may go with 25mm pipe as the exhaust already has a more bassy note than standard and I don't want it to sound like the exhaust has fallen off. :?: :lol:
