Andrew Castle has a dig at modified exhausts!

Anyone see GMTV this morning? They were discussing noise complaints from neighbours and Andrew Castle piped up complaining about traffic noise, in particular bikes. He said a guy near him ‘put a loud exhaust on his bike to make himself feel better’ and it was very noisy. I’m sure the guy had reasons other than just making himself feel better, maybe to make the bike look better, go faster, sound cooler, or possibly to p**s off that silly sod Andrew Castle? That would make anyone feel better wouldn’t it?

I hate Andrew Castle, such a tw*t. He has plastic hair like a Lego man!!:D:D

The Bikesafe police don’t agree that loud pipes save lives, they suggest driver and rider education

Well, whilst they’re being educated, I prefer to stay alive!

agreed

Did you both miss the bit about rider education . … it’s not all about the car drivers you know

The bike cops dont agree that loud pipes save lives!!! yet when they want to be noticed they turn on a very loud siren… double standards me thinks.

There is a massive difference between a siren and a loud exhaust. And they don’t ride everywhere with the siren on.

Think about modern cars for a moment, one of the design goals is to minimise the intrusion of road noise. Also modern stereos have a sensor that automatically increases the volume of the stereo the faster you go.

Also think about biology. The human being is a hunter, the eyes face forward they have evolved to see in front and are also sensitive to movement. The ears are also at better at hearing sound from in front and far less so than from behind.

And finally think about this, being hard of hearing or completely deaf does not stop you from driving. Being partially or completely blind prevents you from driving.

“they don’t ride everywhere with thier sirens on” absolutely correct,strangely enough only when they want to be noticed.

Look we all know the police use blues and twos to be seen and heard when rushing to an incident,we as bikers ride with our lights on to be seen and it’s only common sence that a slightly louder exhaust (not stupidly loud) gives us a greater chance of other drivers and pedestrians noticeing us.

If one person heard me and decided not to pull out/change lane then it was worth every penny.

I absolutely agree with this and Tiggi’s loud pipes save lives! It was proven this morning that no one hears me coming on my squeaky-whisper of a standard exhaust. I can’t wait to change my can and stop the morons from pulling out on me. Grrrrrr

I’ve something v. special in mind to replace the shining cannon that is currently weighing down the right side of my bike (can’t buy it until I sell some stuff tho )

this is quite rich coming from you considering you TRIED to make me sound stupid by your quote of “i saw a silver sv and revving loud saying GRRR IM A BIKER, it must of been you” you complete bellend i revved due to a car in vauxhall cross trying top change lane without signaling while i was filtering

To a car driver with his windows up on the A406 doing 40mph listening to the news with you approaching, from behind, with your exhaust exiting from behind, you’re no louder than the diesel transit to his left which is trying to change lanes. Regardless of how loud your cans are he’s going to see and hear the transit before he sees or hears you so if you’re relying on your pipes to help the driver avoid hitting you then you’re in cloud of false security.

So that I can continue to enjoy the great sound of my bike I find fitting progressively louder exhausts compensates for the incremental damage to my hearing.

Calm down dear!
You did explain that at BM.

Don’t worry, I’d probably have done the same thing.

Not sound technically… good one eh…sound travels at 750 mph roughly at sea level, sound is a wave and eminates in a circle, like ‘the pebble in the pool’ type wave… So travelling at 70mph your sound wave will travel forward at 700 mph relative to you…it will hit the car in a few split seconds…the larger the initial sound pulse the further the sound will travel as the energy of the sound disipates, so the bigger the sound (louder) initially the further it will travel and more likely it is to penetrate the car ahead… So technically what everyone is saying on here is true, they will hear you coming. If they then look in their mirror and see you great. But you guys know nothing about noise…wait until you hear my old KH500 in full song, triple expansion chambers…makes my ears bleed…thats why i cant hear anything anyomore… Got to agree though, Mr Castle cant dance and has the co-ordination of a muppet…amazing he played tennis…ho hum just says what i have always though of tennis players…

I wasn’t suggesting he could outrun the speed of sound but the majority of the sound will be directed backwards and what does come around the sides and forward will be mostly absorbed by the rider, the bike and other traffic. As a driver I’ve seen this many times, bike looms up behind but doesn’t sound loud until it’s going past or in front. I suppose if you wanted to be smart then you could create an exhaust system or just a rear section with a reverse pipe to direct the noise forward and with a resonant frequency that matches 1/4 of the engine speed to make it especially loud.
