HI, what the noise output on a 997 GT3? im an brands next wednesday and want to know the test limit will be tks

U should be ok if u have the std exhaust.

I went to brands this week to get noise tested but failed, i had bypass and the plug out

If there's a track day happening near u, u can always pop along and get noise tested?

not ahead of next week no. i have a standard exhaust so im thinking with the sport button off then at 4k revs it will pass? then just turn the sport button on once on track

Ive been on bedford, plug in sports button off, no probs, they have a strict noise limit. TOwards the end of the day i pull the plug out as im not bothered about being thrown off

From what I've read on here, a 997 GT3 with a standard exhaust system and sport mode switched off is around 102 db.

Generally they ask for 3/4max rev (use to ask 2/3)...6,000rpm is common for GT3. Always give them a good 500rpm less and you should be fine.

Kidhaa 7.1GT3 and I 7.1RS have been numerous times to Bedford (very strict there at 95dB) and never had a problem.

And we were never the only GT3s either.

Sport button OFF of course for static test.

Buy yourself a tester, after the debacle that was Bedford and the noise nazis, I brought my own for £20 off fleabay.

I went to Brands in mine last year and it was fine. Like others have said, make sure sport button is turned off when you do the noise test!

Not the same car granted, but my C2S has consistently measured (with standard non-sports exhaust ) 104db at Goodwood.

I was told to:

a) warm the engine up
b) hold the clutch in which I did and since then it's been coming in at 98db.

Worth trying the both ideas I would suggest!
