How loud is 105db.
Right, risky question this, witht he Night crew signed in.
How loud is 105db. My exhaust is really quite loud, and I don't really wanna turn up at a Track day and get told to fook off, because it's too loud.
So how loud is 105db, is it mega loud? Are there any cars on here that exceed the limit?

i asked this question not so long ago and the responce i got was 105 db was a cossy with the centre box cut out
with makes my car to loud for most track days
but i managed to get a tunable tail pipe insert off e bay that slots into the tail pipe and reduces noise no end
not tryed it on road yet but works at tick over

You will struggle to exceed 105 in your Fiesta, on my 205 I have a group n rally exhaust with no middle box only a small back box. I also have no air filter to dampen the induction noise. I don't have any problems with noise anywhere, even Bedford!
My Toyota has a twin box exhaust system, standard diameter, with cat.
i was recently pulled over by VOSA for a random stop check. When that was measured the reading was 102db! obviously, the car failed (the max acceptable road limit was 90)
what shocked me was i didn't consider the car to be offensively noisey at all!
to get the car to pass i had to weld in silencers over twice the size of the original ones

2.25" no middle box, no cat, 4-2-1 manifold and just a back box.

They served me with a prohibition notice. I had 7 days to fix it. i then had to take it to VOSA for them to pass it. right pain in the arse
if a little 1.5 toyota with 2 boxes and a cat can crack the 100db then i'm sure most of you lot are

Dan, 95bd is roughly the level of noise that a Hammer Drill gives off when it in action.
So, you can probably imagine how loud you'd have to be to get to 105db???
I'd imagine you'd be fine with your exhaust

The Buddy Club spec II on the ITR made 123db on Rolling Road.
The last time i was at Coombe the reading i though was 100db max.
With VOSA how far awy did they measure the sound from out of interest

The copper obviously had very special ears, as he started it, revved it, and then claimed it was too loud. So he gave me a ticket for "Causing Unnessecary Noise."
Well really, it wasn't me causing the noise was it, it was the copper.

It's mainly induction roar now. no bad thing as it's loads quieter on the motorway
See how much it goes down when you get in

I think it's gonna be borderline mate, see if you can get it tested. Maybe have a removavble section put in so you can put a box in it if you need to?

I know I know. Next time I'll stand outside of the car.

they did it from 1 metre from the tailpipe tip, 45degree offset. the car was then revved to approx 4500 RPM (although as my car has the standard clocks with no rev counter they had to guess and ended up just bouncing it off the limiter
Didnt think there was a limit on the road cos of all these fcuking coonts with nova's & paxco's & panda's!
& just to top it off... them weird hairdryer moped things
Oh & harleys& that... one go's past mine everyday & fook me its the loudest thing!

put it on soon took it back to change it to a quiter one
when that link is uploading while you watch it. it sounds like Mick Dundee in Crocodile Dundee 2 when he is making a call to the Aborigines standing on the rock swinging that thing around
The noise test used at most tracks is the static test with the noise meter at 45 degrees to the exhaust exit at 0.5 metre and approx 4500-5000 rpm.
Noise when measured is very strange, 100db to 103 db is TWICE the volume, 100 to 106 is 4 TIMES the volume, and so on.
Any good "one off" exhaust maker will be able to test your car and advise you.
