Hi all. After a bit of advice...
I have had my 458 for about 2 months now, and we're not bonding. I'm wondering if I need to get it on a track to fall in love with it.
There's a Brands Hatch GP circuit day on soon - anyone know if the 458 gets through the noise test at Brands? My caterham was close, so really not sure about the Fezza.

Download an app called decibel 10th.
Hold your iPhone 0.5 metres up and out from the tailpipe at 45 degree angle.
If you have 8 foot legs, rev the car to 3/4 max revs and read the noise level off the phone.
If you don't have 8 foot legs, get someone else to hold the iPhone.
Or call Brands Hatch (google it) and arrange to pop down on a non-race day and they will test you for free.

Personally, I'm not convinced by the IPhone apps. I tried it an was not convinced by the accuracy.
That's why I went to Maplin and spent £30 getting a decibel meter. Works a treat.
Having the concern of a 458 getting thought he noise test……that's a problem I would like to have!

I would have agreed with you, but having bought that decibel meter from Maplins, it said my car was 115 dB. That's why I went to Maplin and spent £30 getting a decibel meter. Works a treat.

It had been 95 dB at Cadwell Park, before I changed the engine from 4 to 5 litres.
So I took it back to the shop.
I downloaded the app. The app said 101. To make sure, I took the car to Cadwell Park, who said 100dB, so I now trust Decibel 10th.
The iPhone apps used to have a limit of about 100dbs (limited by the phone's hardware), but maybe the newer versions are better.
This is interesting although I have no idea about the author's independence or standing:

The readings at circuits vary a lot depending on weather etc, so it's impossible to get a definitive level.

That was a surprise, but I cannot argue against a scientific test.
I agree with the point about track noise tests being inconsistent. My car has measured anywhere between 102 and 108.5 decibels at MSV tracks, which all use the same type of noise meter which they calibrate at the start of the day.
The best plan is to ring up any circuit, ask nicely and they will test you. MSV are very friendly to my certain knowledge (Brands, Oulton, Cadwell, Snetterton, Bedford) and I see no reason why others would be different.

That's a shame. Mine seams to be pretty accurate?It had been 95 dB at Cadwell Park, before I changed the engine from 4 to 5 litres.

Agree with the comment about variance - mine has varied from 88 to 97! As long as it passes I suppose

Is it the MSV day you're looking at ? That has a 101db static limit - I'm going to try and take my 911 to Brands tomorrow to get noise tested but I'm not particularly hopeful even with the exhaust bungs in place.
Yep, the MSV one. My caterham gets under 101, but I'm really not sure about the 458.Don't want to book, go all the way and then just come home!
Did Silverstone last December and there were some Track Prepped Ferrari's there from a trackday "club". They were completely prepped, semi-slicks (may have actually been slicks with the amount of their rubber I picked up. They seemed to be fine, very loud and ridiculously quick!!
So, in short, I'd investigate a "loud" day at Silverstone.
As mentioned, a nice dilemma to have, though I can't imagine not falling in love with a 458......thought granted, it's no Lambo!
