The-Plethora Posted June 1, 2011 Share Posted June 1, 2011 I realise this could vary quite a bit! My work sponsors the ambulances at the castle coombe circuit and they have organised a race day for us in the next few weeks where you get driven round in Ferraris etc. But the reason I am going is because they are also allowing you to bring your own car and take it round the circuit on the day. This is great for me as I get to experience the track when there will only be one or two other cars on so I can see if it's my 'thing' or not. They have to do a check on the morning and we have been given a max noise level of 110 db, I don't think my car is very loud but it is full decat. Would it be likely I would be over this limit? Forgot to ask if anyone brought a db meter to Jfest. Maybe if people with no cats who have had a db check could post up their db figures?

The-Plethora Posted June 1, 2011 Author Share Posted June 1, 2011 It's a stainless steel custom job from http://www.infinity-exhausts.co.uk/ I'll try and get a pic (not sure how much that will help) Quote Link to comment Share on other sites More sharing options...

The-Plethora Posted June 1, 2011 Author Share Posted June 1, 2011 Thanks Homer thats very helpful. I presume a test at 4K RPM is the standard db measure? Hmm, just had a thought, there may be an app or something on android that may do the job, I will have a look. Quote Link to comment Share on other sites More sharing options...

The iPhone ones are limited by hardware and only go to 95db or something Not sure about android but I guess the same applies. Mine was 115 db iirc. Scraped through the noise test. Double decat and nur spec Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted June 1, 2011 Share Posted June 1, 2011 Plenty of aftermarket exhausts on a de catted TT Supra will fail circuit noise tests, and Combe are stricter than most. If there's a track day there before the day you want to take your car out, pop in, and I am sure they will do a static noise test for you, then you will know.
