Fitting Europipes to my 996TT, just wondering if any one has had this make fitted to theirs, and which one you went for. Stage1, Stage 2 Loud or Stage 2 Quiet? Any help for me to make up my mind would be great. The videos they have on the Europipe web site are not great and it is hard to decide which sounds the best.
My other question is regarding dB on track days. On the Europipes web site they give dB readings 1m at 45°. But I have noticed at the track it self that measurements are taken from only .5m in most cases at around 3/4k revs. Surly this would put the 996tt stock exhaust to loud.
Any one with track experience that can shed some light on the subject would be very helpful.

 
I can tell you about Goodwood, probably one of the most marginal tracks noise-wise. The probe is placed less than half a metre from an exhaust and you are asked to rev to about three-quarters of your range. My beast is considered a fairly quiet car, but it registers 100db here.The circuit also has permanent fixed drive-by noise samplers at three locations round the circuit, linked to the local council office, so that any jobsworth can presumably create a stink if they note noise above about 98db.
These regs are of course suspended for the Festival and the Revival ( I think the BRM H-16 F1 car knocks out about 168db at full chat!).
Sounds to me as though your proposed mod would fail miserably.
Not fair, really, because the rear engine layout of our cars means that all the chuffing and wheezing going on also makes it difficult.
ps these regs mean that you cant have more than 5 cars on track at any one time, so no open pitlane.
Believe Castle Combe is just as strict, but not sure about others.
pps by contrast, There are no noise tests at all at Snetterton, an airfield circuit way out in the Norfolk countryside
