Hi all,

I was at Oulton park yesterday, and was tested for noise before I went on track and was surprised at how loud it was.

I was given my windscreen sticker and waved on - but asked the question "how loud is it?' The answer .

"104 decibels! Very loud' was the reply.

This surprised me. Only 1 decibel within the limits of Oulton. From my understanding that will be too loud for Castle Coombe, Mallory Park, Elvington or Bedford.

It has also scared me away from changing the rest of the exhaust.

Have you had yours tested?

Finaly some one has had the same reading as me 104db!!! At Oulton Park!!!

I then had a word with the db test guys at Bedford as they have a much lower limit and they said they had never failed a GTR so to bring it along (I was not with my GTR as thought it would not pass!!) !!

I have booked the GTR on at Bedford for the 16th so I will find out then!!!

I was allowed thru at Oulton Park back in June but never asked what my level was..

No you got me worried about adding my GTC titan to the midpipe I have.....

Limit at Anglesey this month is same as Oulton, 105 dB....

Hi Andy,

don't worry Titan doesn't add to db as much as a cat removing Y-pipe or downpipes. You may benefit from a resonated Y-pipe pipe.... funnily enough my old one going spare :p

What was your dB reading with the full Titan hit?


(he says knowing he may end up owning this too in about 10 minutes...!)

It makes me wonder how all the Evo's got through.

My car was no where near as loud as a few of them.

Is there some fiddle these guys pull?

'OK mate, hold revs at about 3/4 maximum revs'

Hmmm, ok, 7000rpm x 3/4 = 4000rpm!!! ;-) Job done!
