"Noisy" exhausts

--- Quote from: "Evilgoat" ---Rather than the godawful noise a 1.0 Nova makes with a 4" bore exhaust running like a bag of spanners because of the loss of backpressure.

I find them hilarious. The noise just shows everyone that it's only a puny 1.0 under the bonnet becasue it advertises how slow they accelerate :lol:
Bush Tucker Man:
Curious fact regarding Exhaust Noise regulations in another country, but some of you bookworms may know it already
The TVR Griffith is banned from being sold, or registered, in Switzerland as it's too noisy!!!!
How could even they ban such a glorious sound?
The Ant Hill Mob:
These boys are very silly. Basic physics states that noise is a form of energy. That energy has to come from somewhere, and if your car sounds like a bag of spanners and it's got anything less than a 3-litre engine under it's bonnet, you're going to be losing a couple of horsepower going down the street sounding like you've go no exhaust at all.
Silly little boys. When will they learn there's no substitute for cubes?
Lord Shagg-Pyle:
The Good Book says
"No motor vehicle shall be used on a road in a manner which causes any excessive noise which could have ben avoided by reasonable care of the driver"
Regulation 97 Construction and Use regs 1986.
Interpret that how you want.
I have issued tickets for making tyres squeal, loud music, revving of stupid bean can exhausts etc etc. I have to say that I usually take action after a warning has been ignored.
Again the recent topic of seizure of vehicles can come into play.

sorry mate but you are way wide of the mark with that. The reason young driver have small engined cars is not because they want them, its because they cant insure large engined cars.
yes noise may be a bi-product of the combustion cycle but to a point a free flowing exhaust system increases power rather than wasting it as you seem to think. I think you will find there are some modestly(under 2l) engined cars that fly. Let alone the performance that can be gained from a 1000cc bike engine, which massively benefits from a free flowing exhaust.ps my 1277cc bike makes over 170bhp at the wheel...way more than my 3.5l v8.......
