What is it about backfiring?

A Subaru Impreza has just bumbled past the office, with sharp backfires on every lift off. Last night, whilst out for a walk a Golf made us all jump as he flew past us at warp speed in a 30mph limit and emitted a massive backfire on upshift. This was followed a minute later by an Astra VXR which emitted flames and popped and banged its way to a set of red traffic lights.

Is backfiring the new "mega stereo" sound? Is this the yoof must have item for 2016?

I like a meaty sounding car like the best of them but something that sounds like an unexpected shotgun at your ear is not good for the heart.
Martin

It's not just the yoofs.  Jaguar seem to like it too, which pretty much ruins the F Type for me and I heard a new S3 the other day that popped on the up shift.  Sounds rubbish.

The Subaru will be doing it because of a large bore exhaust, they like to pop when fitted with a fruity pipe. Modern stuff is made to pop synthetically by dumping fuel into the exhaust. Sounds more sporty supposedly. I think it sounds a bit shit, especially when it's faked.
Blarno

In fact, the only interesting thing about the engine note on the S3/Golf R is the fake farty pops. Otherwise it's just a dull blurble.
Nice Guy Eddie

As MArtin pointed out, blame the car manufacturers who think it sounds good to have farty noises being chucked out the back of the car. On 4 cylinder shitters it's probably more a fast and furious thing

I regularly see a grey R3 which is driven flat out (in a 30 limit!) but the upshifts produce more of a pop than a backfire. Not particularly pleasant but I don't dislike it either.

The Golf which passed us last night with the bang on upshift sounded more like a weapon of mass destruction which I presume means that it has everything turned up to boiling point with massive boost, dump valves etc.

The F Type is ruined by the stupidly crackly exhaust, it's overdone and very synthetic.

Yep.  Many months ago a V8 S drove down The Embankment in London followed by a current shape Maserati Cabrio and the Maserati sounded absolutely fantastic in comparison.

My car will crackle on a trailing throttle if you put it in Sport but it's relatively restrained. However the Performance exhaust on my old 135i coupe could occasionally fire off a proper gunshot backfire

Talking of things that sound properly good...I was sitting at a traffic light this afternoon on the way back from lunch with a friend, when a Panamera GTS pulled alongside. When the lights changed, I let him go and it made the most gorgeous V8 burble as he accelerated away (he didn't floor it by any means). My chum, it turns out, is a big fan. Likes the styling apparently...
Martin

A Panamera GTS drove past us in Leamington Spa yesterday and I agree, it sounds lovely.  I also liked the looks but the new one has ruined it for me a bit.
TreVoR

Yep, TVR pops and crackles if you feather the throttle on overrun. Speed Six TVRs do it for fun.

I think it's fine for 6 cylinders and above, but small four pots sound crap - unless it is a Subaru.
Martin

A bit of crackle on the overrun is very different.  That I do like, he Boxster does it but only with the sports exhaust on and it's fairly subtle even then.

The first time I heard one I wondered if it was just me that thought it sounded crap.

It sounds like a teenager was involved in designing the sound which is exactly what you don't want when it's the teenager's Dad who is going to be buying it.

Clearly, as a chav with an aftermarket exhaust, I'm in no position to comment on this thread.  

But on the M42 a while ago a man in a BMW 640i did wind his window down, as we all cruised along at 40mph in the managed sections, and and gave me the thumbs up.
Frank Bullitt

Unless it's a Ur quattro in a forest stage, any sort of backfiring sounds shit - be it a chavved-up mk4 Golf, Subaru Imprezza or Jaguar F-Type.  Unless you are 7 years old of course, in which case it's exciting.

One sounds like Thor has just trapped his bollocks between two ships, the other sounds like Larry Grayson has snapped a nail.

More realistic, I feel!

One of the valeters at my last work had a lime green Impreza that would pop, bang and crackle on lift-off even if he was doing 30 in 4th.

I was told it had been mapped that way deliberately.

The 370 can make some lift-off noises but generally the road roar and gearbox whine drown most of it out  
It does do an amusing little burble at a low rev change from 1st to 2nd sometimes but as soon as you try to do it deliberately it stays quiet!
Twelfth Monkey

I heard someone pulling away with gusto in a TT the other day.  Not exactly inspirational, but the series of pops and bangs when he got to the change-up point just sounded silly.  I'm pretty sure it wasn't the rev limiter as the changes were so swift it had to be DSG.
Martin

It is the DSG, it was the same in the S3 I heard.  It sounds rediculous, even my teenage son didn't like it....

I was at B&Q with my Dad at the weekend and a 2006/7 Impreza went past in the car park at a sensible speed.
It sounded great and my Dad commented about it being a nice noise.
He's 84 and has alzheimers!!
PR

You're all weird. I went out in an F-TYPE SVR yesterday and it sounded epic.
Martin

Really?

I've not heard an SVR so I just googled it and it sounds worse than the standard car to my ears, there's a nice sound underneath all the popping/banging/rasping, but it's ruined by all that noise imo.

It's great if you want to shout "look at me", so ideal for the Gumball crowd, but what's happened to 'Grace'?

She tried to get into "Space" on one of Musk's rockets but came to grief on the launch pad.... and don't ask about "Pace"

He thinks he is 17 again, that's why

Are you not contractually obliged to say that though?

I'm sure it's a 100% unbiased opinion!
Martin

He's not that biased.  He still drives a BMW, despite presumably being able to get a cheap Jaguar / Land Rover.
Roadsterstu

It's not allowed in the car park, though.

Is that true?  Is there a car park for non believers / employees with poor commitment?

I work next door to the Ford national parts distribution centre and they have a mix of cars in their car park, it's only the couple of spaces outside the door that always have a Ford (Mustang or Mondeo Vignale usually) parked outside?
Martin

Now it all makes sense.  The manufacturers want to make them sound like BTCC cars.  Great racing though
Twelfth Monkey

Focus RS yesterday, same thing.  Crappy generic turbot-four sound, followed by pop-pop-parp.  Sounds shit.

A performance car without at least a half-decent soundtrack is dangerously close to being just a fast way of getting from A to B.

Genuinely laughed out loud at this
Martin

Just been reading about the F Type SVR in Evo and a fair part of the article is about how awful it sounds.  The latest Jags are mostly the same, so it's not just 4 pots and it's possible to ruin a V8.

Agreed. Audi seem to think some farty noises and the odd backfire counts as a good engine note. And the F Type S's backfiring is annoying - I followed one out of Southampton airport on Friday night and it was making all sorts of nonsensical noises, none of which I liked.

I, too, was depressed by the Evo article - but then I think my car sounds awesome (not too loud, quite motorsporty/metallic when pressed, clearly a V8) and they said that did not sound interesting enough. At some point "interesting" becomes "a teenager's wet dream" and stops being interesting. Even a lot of Italian cars are just too plain loud now.
