Read evidence and context

Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Discussions that contain suggestions: 1

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

Following on from my post about the 98dB levels at Donnington I did some sound testing with a borrowed hand held meter.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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

Following on from my post about the 98dB levels at Donnington I did some sound testing with a borrowed hand held meter. 996 C4 with PSE. Static test showed 95-98dB at 4500 rpm. Driveby showed 95-100dB with foot flat down at around 5000rpm coming past at about 70mph. I stood about 2 metres away for the driveby (probably too close to be fair and too dangerous as the missus was driving it!). Told this to the noise guy at Donnington as I am due to go on April 4th and he said because it may be borderline to get some 'clamp-on' Supertrapps fitted to guarantee entry. http://www.demon-tweeks.co.uk/products/ProductDetail.asp?cls=MSPORT&pcode=MSD344-1705 Has anybody fitted these to the oval tailpipes and are there any known problems like back pressure / overheating? Am I worrying too much as it's my first track day? Migration info. Legacy thread was 124934
