Unfortunatly most 'tuning enthusiasts' put 'sports' exhausts on their cars/bikes as their first 'upgrade', despite the fact that they have no idea wether it actually improoves their stboxes' performance. It just sounds louder. This puts them clearly in the league of antisocial retards imho.
Couldn't agree more, wise words tboxes' performance. It just sounds louder. This puts them clearly in the league of antisocial retards imho.
Yes but what if people would like to excentuate the exhaust note, i.e. make it deeper. On some cars its fantastic.

OK, this may sound weird but after 20 years here I have never heard of this newspaper, Think you may have fallen for a joke. Having said that I would not be surprised by the Nazis here.
Took a bit of searching but I found the original article, pretty obscure thoughhttp://www.thenewspaper.com/news/25/2572.asp
I do spot a little flaw in this plan though

A combination of sound level meters, cameras and computer processors identify these targets of opportunity. Separate microphone and video modules are pole-mounted in waterproof boxes that communicate with a laptop control unit using WiFi.
If it relys on WiFi then it could be jammed pretty easily.

WTF!....That has to be a joke...
They cant tell me that "noise kills"...
What they should be doing is deploying more police to deal with the dustbin clio'd exhaustpipe bregade rather than just trying to rape us for more money!
I agree what a load of balls this is turning out to be! An i have a clio, although it is 100% standard!They cant tell me that "noise kills"...

Being the driver of a particularly 'noisy car' (my kids name for the beast!), I asked my MOT tester what the requirement was for noise restrictions, he replied 'the only potential for an MOT failure was it has to be abnormally noisy!' He went on to make the observation 'Whats Normal for a TVR?'
Unless there are restrictions for new cars, I dont think this will be enforceable in the UK as there doesnt appear to be a requirement.

Is there a law against noise from exhausts anyway? There is never (to my knowledge) a noise check at MoT time. It seems silly that on certain racetracks many cars exceed their noise levels and are not allowed on the circuit, yet the same cars can be used on the road.
My Tow car has a louder exhaust than my race car... Residents must love metps23 said:

What if a lorry is heading in the opposite direction adding to the noise?
Thats a good point, how could they determine which vehicle is causing the noise if there are two going in opposite directions?To answer your question i'm sure it wouldn't be too hard to develop some software that can identify individual noise sources. However as a counter a white noise emitter would also cancel that out [anyone more teckie pls correct me!]
I'm losing the will to live in this world.
Is it me???
Heh - reminds me of when my mate got 'randomly' pulled over in his Evo IX a few months back.
The copper said something like 'That's a very loud exhaust isn't it?'.
To which my mate replied:
'Yeah I had it put on as a safety feature - people can now hear me coming'.
Class.

Couldn't agree more, wise words tboxes' performance. It just sounds louder. This puts them clearly in the league of antisocial retards imho.My celica has a stainless steel system on it, from cat back, and yes its quite loud, but it sounds amazing when my high lift cams kick in! (a sound you realy need to hear is a CTR/ITR/Celica VVTLi 190 etc with a free flowing stainless exaust and a short ram induction kit when in high lift range, simply sexual!)
The stock systems on most modern cars (except ferrari, zonda etc) are so muted and muffled as they have to conform to sound limits when made (98db? not sure on the limit), can get round it like vauxhall have with astra buy fitting it afta the car has been made saying its an aftermarket upgrade.
Also when your engine puts out over a certain bhp/liter ratio you can have a louder exaust straight from the factory, hence why ferrari's are so loud as standard.

I had the same thing for my car (slightly different reason for being noisey but still) and the MOT tester said that noise generally becomes an issue in the MOT when a defective part or damage is causing the noise however, in the province of Hedge End in Southampton were the city planners built a racing circuit out of 4 roundabouts and a McDonalds car park the police have been known to check DB levels from cars (mainly 1.2 Clio's with Dustbins or nuclear missile silo's attached to the back) and APPARENTLY (this is very 3rd hand) people have got those nice pink slips which require you to get a stamp from an MOT centre to prove that the specific area is MOT legal.Unless there are restrictions for new cars, I dont think this will be enforceable in the UK as there doesnt appear to be a requirement.
Dip the clutch and all is well, if it makes that much noise on tick over you must be driving a plane (definatly illegal) or it's a rally car, neither of which are likly to be seen very often.

That is class! dont realy see why coppers can pull you over for a loud exaust when ther is no specific legislation dealing with how loud your car is supposed to be. I know they could argue over disturbing the peace, but tbh you can prob only hear it for 10seconds then its gone, its not like we go around backing up ppls drives late at night and revving it just to wake them up!

There is a Harley Davidson Softail Custom near me which has straight through staggered short shot exaust pipes on! That is f
king LOUD!!! any one who has herd a harley on un-silenced pipes will know what im on about! And on his rear wheel fender has written on it Loud Pipes Saves Lives. There are a few issues here.
Firstly the MOT doesnt cover noise specifically - but construction and use regulations do.
Some few years back(30 plus) I used to regularly get pulled about noisy exhausts (Laverda Jota with track exhaust)and had the pleasure of a drive by test at the local plod shop. I forget what was the quoted limit but seem to remember 98Db - this is now lower according to the Road Vehicles (Construction and Use) (Amendment) (No. 3) Regulations 1989 which state that the motorcycle shall prodcue no more than 73DbA measured as a drive by (!)
So - yes there is an enforceable law in place.
However further observations - noise is merely a form of energy and as such noisy exhausts are probably just wasting energy best converted into motive power - I can understand producing more noise because there is more exhaust where breathing and throughput has been drastically improved but as most exhausts dont do this (and they dont)then alot of the noisy exhausts should rightly be binned.
Or.......... on my V8 US tin I use a DMH Exhaust Cut Out - I can dial in or out the amount of restriction I use in the system. Mostly it is a wide open 4" diameter pipe connected (without silencer) to a V8 650 bhp motor - sometimes I use the cut out to re-route through the silencer...

frequency specific? would it be possible to produce a small unit with a high powered tweeter cheap enough that don't care about it?
Then stick it to the camera detector at some point in early hours, noise is high enough to be unheard by humans, sorry to dogs and bats, triggers camera for the night using up all space on film by the daylight hours?
