Noisy exhausts

Recommended Posts

https://www.topgear.com/car-news/british/noise-cameras-will-know-if-your-cars-too-loud

 

Looks like there is going to be a crack down on cars and bikes, with noisy exhausts. While this article says to be type approved a car has to be under 74dB and that an Aventador is 71.2dB, I presume that this has to be at idle. However, I have seen other articles stating a figure of 90dB before being ticketed, which obviously wouldn't be at idle. 

 

TBH, I approve of this, as I hate noisy cars and motorbikes. I had someone last night at 10.30pm in what sounded like an old V8 revving the hell out of it, and producing more crackles and pops than a bowl of Rice Krispies. Heard it clear as a bell from about 2 miles away, through double glazing. 

 

What I also noted from the TG article is: "It’s also illegal to modify a car’s exhaust to make it louder than it was when it was type approved."

Was only a matter of time until this was brought in. They’re already doing this in parts of America. Although in America its a bit of joke as the law states its whatever the police officer decides is too loud. They’re fining people who have supercars with standard exhausts, they can also issue them with a notice that means they can’t drive their car until the exhaust has been changed. How can you change a standard exhaust to make it quieter? 

 

Its the dick heads that have loud exhausts and rev the tits off their cars at 10:30pm like that idiot you heard last night. They ruin it for everyone else.

I guess it will also act like a speed camera, if you decide to put your foot down you may set it off......Good way to slow people down without having to change the speed limit. I'm not sure the tech if there, what happens if the road is busy, could it not keep setting it off. 

 

Just another way to tax the public

Really torn on this.

 

Living in the middle of the city, this is a genuine issue though. My balcony is about 50m set back from one of the busier and slower sections of Commercial Rd (A13) and no matter what the time of day, you never have to wait more than 10 minutes before someone runs through revving the shit out of their pop/bang map or, worse,  *launching* from a pedestrian crossing. The car maps and pipes have got more extreme in the last 10 years, but bikes have always been the real offenders... I can't remember the last night my dog didn't have at least one barking fit because of some dickhead on a motorbike making more noise than the New Year's Eve fireworks. 3am in a residential area. BANGBANGBANGBANGBANG. All anyone's thinking about is just how tiny the penis being compensated for really is.

 

15 years ago the fart cans and cherry bombs on the scallies' Saxos and Novas were loud, but at least they were predictable... they were a bit annoying, but they didn't make old women and pets jump out of their skin... some of the more extreme pop/bang maps today are about as antisocial as car modification gets and tbh, I really wouldn't mind some of them getting taught a lesson. An A45 launched next to me at some lights a couple of weeks ago (in a 30 limit on the A4 through Marylebone 🙄)... it sounded nothing like a healthy car and quite a lot like an Ack-Ack from WW2 in dire need of maintenance. Growing up, the only cars that made noises like that were the ones were the exhaust had fallen off and there's two lads in there looking pleased with themselves for making a brand new Mercedes do it.

I've always preferred quiet exhausts, even when I was a young revhead.  A quiet exhaust means you can enjoy more of your car's (or bike's) performance envelope without attracting unwanted attention from the police or bystanders (who may react by asking the police to "have a chat" with you).  I don't feel the need to have people swinging their heads around as I go by making a great racket (and trust me, most of them will be thinking about the inverse proportional law relating to loudness of exhaust vs size of penis, not "what a great sound, I must do something like that to my car").

 

Feel free to have a totally different opinion, but remember that a loud exhaust is being inflicted on all ears within hearing distance, not just funnelled back into the interior of the car making the noise.  If all the extra noise was only inside the car I could care less - maybe we need an exhaust version of the soundaktor, and have it only functional if all the windows are fully up ?   ;)

I’d always thought that was why Soundaktors/ artificial piped induction noises etc were installed in the first place. To give an impression of engine noise inside the car while giving a relatively quiet exhaust to the outside world a la Golf GTI/R, Fiesta ST. But this solution does not find favour with all.

That said - I have to own up to having a Janspeed Extractor manifold and exhaust system on a Ford Escort 1.6 with Twin Carbs, high lift cam etc.   But I was 35 years younger.Haha.  So it might bean age thing too.

Yeah, I think it's probably an underspoken point that interiors have got a lot quieter, especially in the more premium marques... manufacturers do stuff like Soundaktors to bring the engagement back in their performance models, but any real petrolhead is going to want to turn that off and hear the real sound of their engine... which now needs to be x-times louder because the cabin is so well insulated.

 

Sticking a piezo mic on the tailpipes and routing the sound through a hidden speaker in the rear of the car would possibly be a better starting point than creating a whole different noise on top with a Soundaktor.

It's only going to be deemed more and more anti-social as electric cars rise in popularity. Not to mention that those with loud exhausts will stand out even more - therefore being an easy target for police etc.

I've never had a problem with the standard R exhaust sound....the in-laws and wife both still say they can hear me coming before they can see the car!

I guess so. Which leads to the question I have asked, as to who is the noise really for? Is it for the driver or for the "benefit" of others. I know some love the soundaktor, some hate it, and some are in the middle. I have dialled it down to 25-30% and that suits me. However, on a long drive (600 miles) I got out the other end, and while the body was fine, my head was pounding a bit. Must remind myself - on long journeys, set engine noise to comfort.

To me, the R Estate (not sure if much different to hatch) is about as loud as I want it. The Mrs thinks it stupid and far too noisy as it is. But as for drawing unwanted attention - absolutely. I was in France not so long ago, and coming up to a peage, there was a large group of gendarmes. I saw them eyeing up the car and debating whether to pull me, as I feathered the throttle to try and be as quiet as possible. 

 

As for the tool in his stupid car last night, was talking with a bloke who lives a mile away and he had got the hump a bit, as the car passed his house at speed making the godawful noise and had woken him up.

The joy of a valved resonated exhaust on an R, you can have it nice and quiet when you want or loud as you like in the right circumstances/environment

 

The idiots who have decays and unresonated set ups, non valves and some even with back boxes removed are the cause of this and it's fair enough imo.

Those who want it loud regardless of whether it actually sounds any good are going to ruin it for the others...

Personally I don’t like being told what to do so this is another nail in the coffin and yet more rules but with so many dicks about it’s kinda inevitable.

I live near (ish) a bypass and now and again you can hear some real nice cars tearing off down the road after the junction. It doesn’t annoy me and I like guessing what car it is that’s just been “sent”. A few Aston’s an rs3 an few f8x m3/4 and a lovely e9x m3 I often hear and don’t mind them at all.

That being said, the specific maps for all the bangs that are getting more popular recently are probably to blame for this new rule too - they sound crap and are just noise and will ruin it for the rest of us...

It's common sense, you see people doing videos on residential streets and laughing...

Unfortunately if you don't tell some people what they can and cant do they just go to the extreme...

I do lots of long trips in my T5 van and found the road noise was quite tiring (please try to ignore the obvious pun about tyre noise).  I ended up trying some noise-cancelling headphones and they reduced the noise-induced fatigue considerably.  I can still hear emergency sirens if needed, but I did have to turn up the volume to hear my music properly.  The difficulty in hearing your passengers could be considered a positive (depending on circumstances ;) )
