Is the "offending" exhaust sold as track use only?
If not then the manufacturer must know something that we don't as they would be selling illegal exhausts?

Surely if all these exhausts were illegal then the likes of Scoobyworld etc etc would be able to sell them without stating, not for highway use. Like they do with the afterburner extreme.

A good mate of mine is a traffic cop, and a subaru/performance car enthusiat too, I have shown him this thread and asked him for his clarification;
The check is legitimate, could be Police or be the Police working in conjunction with council who are the usual ones to test noise, however there are rules around it and they are these. Device had to be Calibrated prior to test but only once at beginning of day so should be in notebook of whoever is conducting test. There should be a 3 metre space around rear of car.
Device should be
1/2 metre out, 45° angle and 200 mm up from exhaust. Noise level is set at 101DB, that's it, anything less is legal for noise. Tested at 2500 Revs or half of the max Revs whichever is greater.
SVA is 101DB so measured the same.
Some imported cars don't have UK test noise so get type approved so can be louder than standard.
A ticket can be issued though for having a non standard exhaust not based on a DB reader, just the fact it is blatantly not standard and louder than it should be, construction and use offences.
Hope this helps, personally I have never had any trouble (my exhaust is around 100db's trackside tested) but if you give them a reason to pull you over by driving silly etc, then they're going to give you a ticket or trouble back.

Here is the answer - almost
Ok guys here is the answer....I think!!!!!!!!!! Apologies if it is long, I have summarised what I think are the important bits.
The Road Vehicles (Construction and Use) Regulations 1986 as amended by Motor Vehicles (Construction and Use) (Amendment No. 4) Regulations (Northern Ireland) 1999
http://www.legislation.gov.uk/uksi/1...chapter/K/made
http://www.legislation.gov.uk/nisr/1999/235/body/made
(Please let me know if this is supceded)
---------------------------------------------
Section 55: Silencers
(1) Every vehicle propelled by an internal combustion engine shall be fitted with an exhaust system including a silencer and the exhaust gases from the engine shall not escape into the atmosphere without first passing through the silencer.
(2) Every exhaust system and silencer shall be maintained in good and efficient working order and shall not be altered so as to increase the noise made by the escape of exhaust gases.
So it looks like they may already have a case to do you for an after market exhaust as they are invariably all louder than stock. However these is no statute that dictates how to make this comparison, so where an exhaust is slightly louder exhaust than stock they would have to make a comparison with the standard vehicle and this is unlikely. Where it is much louder than stock they may just do you under the next section.
The 1999 amendments are not particularly relevant as I read them.
---------------------------------------------------
Then.....you have to go to this directive which supceded prior directives......
http://eur-lex.europa.eu/LexUriServ/...92L0097:EN:NOT
5.2.3.4.Method of measurement
5.2.3.4.1.Nature and number of measurements
The maximum sound level expressed in A-weighted decibels (dB (A)) must be measured during the operating period referred to in item 5.2.3.4.3.
At least three measurements must be taken at each measuring point.
5.2.3.4.2.Position of the microphone (Figure 2)
The microphone must be located level with the exhaust outlet or 0,2 m above the test-track surface, whichever is the higher. The microphone diaphragm must face the exhaust outlet at a distance of 0,5 m from the latter. The axis of maximum sensitivity of the microphone must be parallel to the track surface at an angle of 45° ± 10° to the vertical plane defined by the direction in which the exhaust gases are emitted.
The microphone must be positioned to the side of this vertical plane which gives the greatest possible distance between the microphone and the vehicle contour.
If the exhaust system has several outlets, the centres of which are not more than 0,3 m apart, and which are connected to the same silencer, the microphone must face the outlet closest to the vehicle contour or the outlet which is the highest above the track surface. In all other cases separate measurements must be taken at each of them, the highest figure recorded being taken as the test value.
In the case of vehicles fitted with a vertical exhaust outlet (e.g. commercial vehicles), the microphone must be positioned at the level of the exhaust outlet, facing upwards with its axis vertical. It must be positioned at a distance of 0,5 m from the side of the vehicle closest to the exhaust outlet.
Where the design of the vehicle is such that the microphone cannot be located as shown in Figure 2 because of the presence of obstacles which form part of the vehicle (e.g. spare wheel, fuel tank, battery compartment), a drawing clearly indicating the position for the microphone must be made when the measurement is conducted. As far as possible, the microphone must be more than 0,5 m from the nearest obstacle, and its axis of maximum sensitivity must face the exhaust outlet from the position least concealed by the above mentioned obstacles.
5.2.3.4.3. Conditions of engine operation
Engine speed must be stabilized at three-quarters of the speed (S) at which the engine develops rated maximum power.
When constant engine speed is reached, the throttle must be rapidly returned to the idling position. The sound level must be measured over an operating period comprising brief maintenance of constant engine speed and the entire deceleration period, the maximum sound-level meter reading being taken as the test result.
5.2.3.5. Results (test report)
5.2.3.5.1. The test report drawn up for the purpose of issuing the certificate referred to in Annex III must indicate all relevant data, particularly those used in measuring the sound of the stationary vehicle.
5.2.3.5.2. Readings, rounded off to the nearest decibel, shall be taken from the measuring instrument.
Only those values obtained from three consecutive measurements which do not differ by more than 2 dB (A) respectively are taken into consideration.
5.2.3.5.3. The highest of these three values shall constitute the test results.
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!
So now we know how you measure the sound!!!!!!!!!!!!!!!!!!!!!!
BUT
It looks like the wire wool in the exhaust trick is a no no:
5.3. Exhaust systems containing fibrous materials
5.3.1. Fibrous materials may not be used in the construction of silencers unless suitable measures are undertaken at the design or production stages to ensure that the efficiency required to comply with the limits imposed in item 5.2.2.1 is achieved on the road. Such a silencer is considered to be efficient on the road if the exhaust gases are not in contact with the fibrous materials or if the silencer of the prototype vehicle tested in accordance with the requirements of items 5.2.2 and 5.2.3 has been put into a normal state for road use before the sound-level measurements are taken. This can be achieved by using one of the three tests described in items 5.3.1.1, 5.3.1.2 and 5.3.1.3, below, or by removing the fibrous materials from the silencer.
So as I read it plod can remove your wire wool and retest the car!
-----------------------------------------------------
And where can they test you car, and in what conditions.......here's the answer:
5.2.3.3.1.Test site (Figure 2)
Any area not subject to significant acoustic disturbance may be used as a test site. Flat surfaces which are covered in concrete, asphalt or any other hard surfacing and possess a high degree of reflectivity are particularly suitable; surfaces consisting of earth which has been tamped down must not be used.
The test site must be in the form of a rectangle, the sides of which are at least 3 m from the sides of the vehicle. This rectangle must not contain any significant obstacles, e.g. an individual other than the observer and the driver. The vehicle must be positioned within the abovementioned rectangle so that the microphone is at least 1 m from any kerbstone.
5.2.3.3.2.Meteorological conditions
Measurements must not be made in poor atmospheric conditions. It must be ensured that the results are not affected by gusts of wind.
5.2.3.3.3.Ambient noise
Readings on the measuring instruments produced by ambient noise and wind must be at least 10 dB (A) below the sound level to be measured. A suitable windscreen may be fitted to the microphone provided that account is taken of its effect on the sensitivity of the microphone.
-------------------------------------------
Still going........
The sound bit...............
5.2.2.1.2.2.
- with an engine power of not less than 150 kW (201 bhp)
80 db
BUT...there's still more!!!!!!!!!!!
just to confuse things this is the sound levels for moving vehicles..................................
---------------------------------------
Section 56: Noise limits—general
(1)(a) [A vehicle is within category (a) if it does not fall] within sub-paragraph (b) or (c)
(b) engineering plant;a locomotive other than an agricultural motor vehicle; a motor tractor other than an industrial tractor or an agricultural motor vehicle; a public works vehicle; a works truck; or a refuse vehicle
(c) has a compression ignition engine; is so constructed or adapted that the driving power of the engine is, or by appropriate use of the controls can be, transmitted to all wheels of the vehicle.
Now this is interesting in my view, as cars that fall within category (a) can produce a different level of noise. (b) is irrelevant, but (c) as I read the letter of the law includes diesel cars and all wheel drive cars, or in other words Subarus, Quattros, Range Rovers etc.
but I can't find anything in the 1999 statutes that supercede the 1986 statute for a stationary vehicle.......which seems to suggest that a Subaru falls in to the all wheel drive and diesel category and is therefore 82db using the above testing methods.
ONE FINAL BUT
82db seems too low IMO, so please provide a link to any higher db rating that you may have (not a link to some crappy blog either, let's do it properly)
The Road Vehicles (Construction and Use) Regulations 1986 as amended by Motor Vehicles (Construction and Use) (Amendment No. 4) Regulations (Northern Ireland) 1999

A quick search found this - http://www.suffolk.police.uk/safetya...fications.aspx
Surprised me and will probably surprise a lot of other members!!!

Basically because they have more important things to be doing than being picky about my lights. The sargent also then said that they were a good idea as the car is longer than your average car and they were like markers to show other road users that it was a longer vehicle
So what I'm thinking is an aftermarket exhaust is a modification, true. But if you was to be pulled over by an officer of the law because your exhaust wasn't standard, would this also put them in the same catagory as the above and needing a bomb shoved where the sun don't shine?

I know it's not the same thing but I have a stretched limo I use as my business and recently a friend and I changed the opera lights (the ones that run down the side of the car between the windows) from a very dim and hardly visable neon type of glow to a led blue lighting glow. Now I was a bit dubious about the colour and went to my local police station to ask if they were legal or not. An ex sargent came out to the car and said although they are illegal (in theory as lights that face front need to be white and lights that face the rear are to be red, but these lights face sideways) he suggested that if I got stopped because of these lights then the officer in question deserve to have a bomb up their ****! His words not mine

On my v5 (log book) it states
u sound level:
u.1 stationary(dB(A)) 83
u.2 engine speed (min-1) 4500
u.3 drive-by (dB(A)) 71
on my05sti UK but car has ppp fitted from new,so ?

i got pulled last night by a normal policer officer (not traffic) i have a 99 uk classic with an unbranded 5" tailpipe exhaust, i bought a bung for it as it was really loud and also the CAT is currently back on the car because it was MOT'd last week.
so compared to normal its fairly quiet, anyway he told me that i needed to get it changed, it was clearly non standard and if he was a traffic officer then a ticket would have been issued. i was polite and he wasn't being a dick about it, just said i need to get it changed or at some point i will be issued with a fixed penalty

I know of a 599 owner who has such an exhaust fitted, normally it's nice and quite, flip a switch and the valves open and suddenly you have an awesome straight-through exhaust.

(2) Every exhaust system and silencer shall be maintained in good and efficient working order and shall not be altered so as to increase the noise made by the escape of exhaust gases.
The exhaust would not have been altered tbh , I think this refers to bikes putting micron type additions

This seems ridiculous tbh.. I can understand stupid loud exhausts 110dB+ driving up and down housing estates all day but anything less than 100dB is not loud IMO. The police should spend there time looking at dangerous/uninsured drivers etc instead of trying to bully money out of enthusiasts! Subscribing to the thread to see what evolves!

its all nads, i measured a uk std centre pipe and its 2.5inch, however it does have a expansion box, all said and done mine now has .no larger internal than std
headers uppipe, 3"to 2.5" downpipe, 2.5" unresanated centre section and scoobysport backbox, 74db on tickover 96/97 at 4500rpm . no loss of boost or power, all i did was had the backbox opened up. inside is just a pipe with loads of holes with wire wool wrapped round it, i removed the wirewool cleaned out all the holes and repacked it with motorcycle exhaust packing, off ebay then had box tig welded back up, can't see its been done total cost of backbox surgery £40. happy me happy plod . just proves you don't have to take out a mortgage for a trackday system

headers uppipe, 3"to 2.5" downpipe, 2.5" unresanated centre section and scoobysport backbox, 74db on tickover 96/97 at 4500rpm . no loss of boost or power, all i did was had the backbox opened up. inside is just a pipe with loads of holes with wire wool wrapped round it, i removed the wirewool cleaned out all the holes and repacked it with motorcycle exhaust packing, off ebay then had box tig welded back up, can't see its been done total cost of backbox surgery £40. happy me happy plod . just proves you don't have to take out a mortgage for a trackday system

Agreed Tommy, although OP advises his mate was out driving & they pulled him over to follow them to some mad supermarket. If tearing about housing estate & driving folk mental I can kinna understand a bit but if out on a daily drive this is insane!

Thanks to above researchers who posted some facts on the topic. I don't like how these measures are greatly biased towards the "opinion" of the enforcer.
Where will it end though? Wouldn't be surprised if the EU passed new directives to limit how/when we can pass wind in public. Quite likely that fines will be imposed for polluting the atmosphere; causing un-necessary aural disturbance to persons in the vicinity; offending certain cultural norms; & possibly contributing to global warming.
Good to see how well our tax money is directed towards important causes that make everyone's lives so much better, safer, & enjoyable.
