[Closed] Backfiring cars - is this a ‘thing’?

Or is it just local to the Westbury area? I’m continually hearing loud bangs from modified cars driving around the trading estate where I work, as I’m outside all day maybe I’m noticing it more, but it’s not something I’ve been aware of previously. Sounds stupid, and it can’t help with the longevity of things like the exhaust system.

Yes it is a thing - tradionally it was the sole preserve of the super-aggressive cams and/or turbo-related rich fueling of a racing car, but nowadays any chav can have their hopped-up GTi do it.

I am occasionally allowed to help service a 1990’s rally car

it has “anti-lag” which kinda injects fuel when you decelerate in case you want speed up again quickly.

If you don’t, the spare fuel gets in to the hot exhaust pipe and goes BANG!

Some people think a Vauxhall Nova* sounds Coooool if it does the same, so find ways to mimic the sound.

Other cars are knackered and do it anyway.

*other newer seriously coooool cars are available

Our mighty* Ibiza 1.4 16v, pumping out a Tarmac bending 75bhp has never, and is highly unlikely to ever, partake in such shows...but only as it's the estate. If it was the 2-door, she'd pop and bang like a drum kit...

Yup a few of the scrotes up our neck of the woods have jumped on the bandwagon, terrible.

Of course when i use to flick the kill switch off , while on overrun on my cbr6 & flick it back on the resulting gunshot was highly amusing.

Quite a lot of standard 'performance' cars seem to be mapped as standard to give a bit of a pop-pop-pop when the throttle is heavily lifted-off.

There's a bloke round the corner who I assume works for the local Mini dealership, given that he has a different Mini every few weeks. Every time he gets the JCW ones, you can hear him careering down the road, accelerating hard then lifting off to get a bit of a pop-bag from the exhaust. He does it repeatedly all the way down the road. Tosser.

My dad's ride-on mower does it. Quite alarming when you are sat 12 inches from the exhaust. Think it might be an issue with the (manual) choke.

Can we join the cooool gang?

My motorbike can shoot flames a good 5 feet out of the exhaust. But if anyone else does it, they're dicks

Think of it as a mouthbreather early warning system.

its actually unburnt fuel ignited by static sparks from blue and white sportswear. FACT.

My mate used to turn the ignition off in his Skoda Estelle then turn it back on again under throttle to get a ridiculous backfire.

We were children though.

Flat shifting in my old Honda at 8,600rpm would produce some hefty flames out of the exhaust, but no backfire bangs.

My Cooper S does it from standard, lift off/change gear and it pops and bangs and it now has a stainless Cat back performance exhaust so can be quite loud. When I first got it the wife borrowed it for a couple of days and said she didn't realise it did it all the time she thought I made it do it 🙂

It's a retard  'thing'.

My 1949 Matchless 350 has a manual advance lever on the bars.  While on overrun downhill, the lever can be shoved back to full retard for fully awesome popping and banging.  Most excellent for alerting nervous horses to your presence.

An Astra VXR has the retard affixed to the drivers seat rather than the bars.

I’ve noticed it more too. The 80’s are back! I might join in and have my Zafira convertedto do it. Zafiras are cool right?

Antisocial noise pollution. Loud motorcycle exhausts are a similar problem.

The other side of the workshop wall theyve been sticking an RS engine back into a Rally Escort. It sounds like an artillery range at work at the moment.

My previous motorbike (TL1000) used to do it a fair bit when the throttle as shut off quickly, sounded like a shotgun and used to set off car alarms. New bike (gsxr1000) doesn’t back fire but still gets a nice burble on the over run when it’s nice and cosy.

My brother has a Nissan Pulsat GTi-R many years ago with a 4” straight through exhaust that used to spit blue flames about 6ft out the back under hard acceleration. Sounded like a jet fighter aswell.. awesomeness innit.

Loud pipes save lives for motorcyclists. I used to do the whole accelerate hard, switch off then back on again really quickly in my Nova in my younger years until a massive flame melted the paint on my bumper.

Im still 18 in my head.

A faceache friend of mine has recently spent about £600 getting his Lancer Evo (on which he's already spent a kings ransom on carbon bits and shiny bling) remapped to fart, bang and whistle to order.

He also specialises in blocking the maximum number of car parking spaces whenever he's out with it. And then bragging about it on Instagram :-/

But weird since he's actually a really sound guy at any other time...

What will our 2nd hand electric cars be modded to do in the hands of bored young men in the 2nd half of this century? There are worse outlets for 'individuality'.

Loud pipes may save their lives but the indiscriminate rev-bomber should be put to death.

<div class="bbp-reply-content">

Erm, the thing with motorbike exhausts is that they point backwards. I think there does seem to be a theory that 'the car drivers must hear me because my exhaust is really loud' when the reality is that the exhaust don't actually sound very loud until it's practically gone past.

You can hear my bike coming before you see it anyway. It’s not excessively loud or it wouldn’t pass an MOT, if it alerts car drivers to my presence then I’m happy to be labelled as antisocial when I’m out on it.

****s with stupidly loud cars and motorbikes are the oone thing that makes me want to move house. It actually quite up sets me sometimes.

I like my house and have a lovely garden and we love to eat outside and spend as much time as possible out there when the weather is good. But some times we literally can't hear each other speak. Which is lovely when the kids are trying to tell you about their day.

****s the lots of them. If you want drive/ride like a ****, go to ****ing track you annoying ****s.

Sorry but I feel strongly about this as it actually affects my home life.

When I took it around Europe last year the centre section of the exhaust on my Porsche 924 cracked. Whenever you lifted off the accelerator it popped and banged as petrol went straight out of the back of the engine. Once we'd bodged it up a bit with some mastic, metal sheet and jubilee clips to tone it down a  bit it sounded AMAZING. Very antisocial though.

In an old knackered 80's sports car like that I think it sounds pretty cool, but in a Ford Focus RS tootling around a town at 20mph it sounds pretty daft.

We live in the Derbyshire Dales and sporty engine noise is a background noise for about 30 seconds most sunny evenings. I can't say I mind it much.

I think it's daft that new cars like the current Cooper S does this. It's not a race car running rich -  it's a sensible hatchback ffs.

A bit of a burble on overrun is fine, the occasional pop in something appropriate is okay too.

Some **** in a 1.4 Corsa he can piss off

Shame people still see cars as "fun" things to mess around with and not just devices to get from A to B, but that's the way it is in this screwed up ol' world.

What do you mean second hand? New cars are already available which play a "brrrrm brrrm" sound through the speakers. Once we have quiet electric cars you'll be able to download sounds like ringtones. Imagine having that Nokia diddle-dee dot diddle-dee dot diddle-dee dot dee coming out of the fake exhaust pipe.

it has “anti-lag” which kinda injects fuel when you decelerate in case you want speed up again quickly.

If you don’t, the spare fuel gets in to the hot exhaust pipe and goes BANG!

Iirc anti-lag uses an additional injector that squirts neat fuel into the exhaust before the turbo. When you change gear and the flow of gas from the exhaust slows the turbo slows down. The fuel from the anti lag ignites during this lull and reduces the decrease in turbo rotation speeds.

For those who aren't top flight rally drivers it makes a good noise, exhaust flames and reduces the life of your exhaust and turbo significantly.

Had a suitably hooliganish car years ago that did it a lot when it was started from cold.

On a frosty winter morning, a blip of the throttle as I sat warming the car up was usually enough to set off multiple car alarms in my street😳

My KTM and my Cinq do it on overrun - they're just overfuelled. My first Abarth was programmed from the factory to do it at certain shift points. The second one is EU6 compliant so doesn't (well does from 3-4 at 5600, sometimes, if you're very, very quick shifting). Its completely pointless, fairly antisocial and always made me giggle when it does it.

Of course cars can be fun - to view them solely as a means of transportation is pretty depressing.

Hardly makes it a screwed up 'ol world to think like that.  Hey, live a little 🙂

Shame people see "food" as something to which flavour can be added, as an occasion to enjoy time with bourgeoisie "friends", instead of just a means of providing sustenance to allow the individual to produce for the furtherment of the glorious Mother State.

Been wondering about this, do these cars have to get remapped to pass mot? and standard exhaust fitted then reset to 'tosser'  after? do they have to inform insurers? lots of the ones near me seem to be gtd deisels make a hell of a noise and push out thick clouds of black smoke.  why would you want to make your car sound like its fkd,  blew an exhaust of a car years ago and drove for 2 hrs it was deafening and a bit shit but that on a daily basis no ta

Cars are awesome, yep. The planet needs more and needs more fun ones. Can't get enough of em. Let's just turn everywhere into roads so people can have their fun.
