IS IT ILLEGAL TO HAVE MODIFIED EXHAUSTS & POP & BANG MAPS?

With modified exhausts being a very popular modification here in the U.K, doing so or having one exposes a list of complicated rules and regulations that can be very hard to understand!
From pop & bang maps, sports cats, decats all the way to a simlpe loud exhaust system, police officer MPS OWEN MESSENGER helps explain all with some very helpful input from the team at Milltek Sport and a very special guest.

[@ethanosullivan4649]

It's nothing to do with them being a low volume manufacturer the reason they can be loud is because they come out the factory as loud

[@terrybrown6057]

Low volume cars still have to be type approved (homologated). Lower volume cars such as a one off custom made car goes through IVA test. This test still has the same noise restrictions as type approval. BUT You can have a noisier exhaust based on the age of the car. So if your car is running an exhaust that was legal back in the day, it's still legal now. Your not forced to remove what is legal from new. I have a bike engine car revving to 13,000rpm.. The system has one exhaust can running along the side of the car. IVA approved. Manufacturer supplied silencer. It doesn't need or have an ID tag welded on. That's just how they were made. Government approved. So your video is incorrect Teddy bear.

The logic outlined in the video is incredibly flawed. Lets imagine a scenario where I have to replace my exhaust for example because of corrosion. If the OEM part is discontinued and no manufacturer makes a pre approved, ECE compliant replacement, then it is physically impossible to ever have a legal car. Rediculous law. By extension, this also dictates that every single exhaust shop in the country that does not use off-the-shelf items, illegal.

[@xabre9995]

It's not illegal to fit or sell an aftermarket non-compliant exhaust to your car. It's illegal to use them on the road.

I think its great to educate everyone on this topic with this video, but there are a few things that dont make a lot of sense. You have a segment talking about how pop and bang tunes can cause detonation, and how that ruins engines. However, the RS has been tuned to have bop and bangs, as you would definately give it a new tune after fitting a fully different downpipe/cat/exhaust given its a turbo car. Whats the point of saying dont get a pop and bang tune, and then getting one yourself? Also, when mentioning the seat with detonation related engine wear, i dont think you can just say its due to the pop and bang tune, i would argue its most likely the tune as a whole not being suitable to prevent knock, in part due to elevated temperatures. But you can’t look at detonation on an engine and say ahhh yes thats because of a pop and bang tune.

[@filmboy18]

The Leon story was such bullsh**. I have a cupra 300 and they pop and bang from the factory fairly loud even with the stock exhaust system on. They sound mental with an aftermarket exhaust even without a pop and bang remap. Pop and bangs don't cause any damage at all so long as the tuner isn't going crazy and turning off engine protections in the ecu.

[@richardbrown8271]

Sergeant dibble 😂

[@robmoto8210]

Pops and bangs are the result of unignihted fuel in the exhaust that catches fire. Not in the sylinder. Btw they wouldn’t make an engine that isn’t supposed to withstand high pressure and explosions.

[@davideyres955]

They were an invention from rallying where you deliberately sent unburnt fuel into the exhaust to ignite so that the turbo spun up. I believe they also used the spark to ignite the mixture in the exhaust cycle on a gear change. But you never get anything for free. Motor manufacturers put a hell of a lot of work into making cars reliable and a lot of these aftermarket mods actually make cars slower or remove built in safety features which are there for longevity.

I lived in America for a half a decade and cats where not required in that state, yet some modified cars still had them so that that the exhaust wouldn't sting noses or smell funky. It's something like 3% of all cars had their cats removed, some percentage got stolen and never replaced and everyone else, the 'normies' if the mechanic tells them they need a new cat, they just get it done and keep the car factory. Almost as if we don't need mandatory cat converters at all because most people will never take them off and those that do are such a small percentage that they're not going to turn cities into eye burning hydrocarbon fog clouds.

About 14 years a go we rebuilt a 3rd gen 1991 chevy camaro, tried to get original steel exhaust couldnt get one even in America, only a thing caled a magna flow available. We decided it was to loud so we fitted an extra silencer at the front y pipe which brought it to exceptable level, the fuel system was to high on emissions for the UK so webber built a carb for the engine which brought the car well under the UK emissions level. I asked the mot center about this new law when I took it for its mot in febuary they said it is for modified cars your car is still standard. The magna flow is just a stainless steel version of the original exhaust as for the webber it runs a lot smoother but it lost a lot of power from the holley but it got the emissions spot on.

The precedent set as a result of this is frankly frightening. The vast majority of factory exhaust systems fitted to cars of all types and pricepoints do *not* have EC markings on them and this includes the catalysts fitted to them. The vast majority of police officers are not clued up on cars. The DVSA have effectively put the power to prosecute and profiteer off the motorist entirely into their domain and manipulated it in such a way that if you are in breach or in compliance to the precedents they themselves have set is entirely within the purview of themselves or a *very* fallable(and proven biased) human being wearing a uniform and badge. I understand the purpose of this video is to inform, not endorse but I echo the sentiments of every other commenter here suggesting this is a massive over-reach.

The guy talking about pop & bang maps is right about them causing engines to deterioate quicker. I had a friend with an older Skyline who had a hard cut limiter and it was same concept with dumping fuel in but eventually all the detonation cracked a valve. Some of the emissions stuff on older cars, particulary diesels is pretty silly. Example: You have an older diesel with a cat, but no DPF. Cat is clogged up, and doesn't work any more but passes the MOT as the only test is to ensure it's visually present, since it doesn't impact the diesels emissions test in any way. Same with EGR

[@filmboy18]

So an over aggressive hard cut limiter did the damage then? Just think of all the cars that come from the factory today with "pop and bang" programmed into the overrun. People need to realise if you don't go crazy with the bangs on overrun it won't damage anything. It's scaremongering.

@@shamar8529 I'm aware. I was issued a prohibition notice for a modified back box about 2 months ago, I had an aftermarket cat back installed. No downpipe or modifications to the CAT, they're clamping down on it big time, I was asked if the cat back system was EC approved by a DVSA officer.

I have a question to anyone that can help me I'm looking for a cheep affordable exhaust for my 2011 seat leon 1.2 tsi and I also need it to pass a MOT what exhaust could I have on my car

[@rb-1236]

The stock one

[@gj3281]

So in summary the previous Scoprion exhaust fitted to the focus wasn’t road legal… proof even the police struggle to understand the law! Scorpion specifically state on their website that their exhausts are NOT EC approved. However also a bit misleading, will an EC approved exhaust be 100% legal, of course. If an exhaust isn’t EC approved does it mean it isn’t road legal, not necessarily. If I get a custom exhaust made to the exact same spec as an EC approved one then it’s going to be compliant as it won’t be any louder than the stock system. All in all great video and super helpful.

[@colinhall8998]

Funny, call the police about a noise complaint and they say contact the council. If there’s money to be had with a fine they’ll prosecute!

[@azer9237]

P&B maps can have benefits, if done extremely well. Small burbles can actually keep your turbo spinning and allow for better pressure after a shift. Just depends on how much extra fuel is burning, and from there you can manage engine damage. The massive pops and bangs are rediculous. There's no point.

[@phoenixmotorsport647]

Interesting fact - "pops and bangs" actually came from the rally world and what is was was a device that reduced the amount of lag on turbo charged car by allowing small amounts of fuel to be burnt off throttle so there was extra exhaust gas to keep the turbo spinning longer and therefore reduce the spool up time. Rally cars had to be able to turn it off when not on a stage. Of course the boy racer brigade started copying on their 1.2 corsas and the rest is history

[@filmboy18]

Anti lag is way way way more aggressive than your average pop and bang remap. With real anti lag you find yourself replacing turbos quite often because of well... the excess heat.

[@phoenixmotorsport647]

@@filmboy18 I get that - I compete. Im just saying thats where the craze started. Originally it served a real person for teams that had stupid amounts of money and rebuilt the engines very frequently. Then what happened is bill in his 1.2 Nova decided he wanted to sound like that because it was "cool". And a new remap was born to annoy people the world over (and for those watching that did it to their road cars - it doesnt make you faster - just annoying)

[@japfourme381]

Most of these things are illegal, but it will never stop people modifying or adapting their cars, it’s all about personalising them to their own tastes! Same with motorcycles and loud exhausts!!

[@Revvs7]

I advise motorcycle users to fit loud exhausts on their bikes as it's much safer. So many times I've had cars cut me off because they didn't know I was there but as soon as I fitted a loud exhaust it's been easier for cars to notice me and I've never had an issue since. If the government cared about motorcycle safety they should allow louder exhausts for motorcycles.

[@poitynine]

Used to have a cat back straight piped fiesta zetec as my first car, police used to pull me over and check my car and then tell me it’s legal and let me go. Never got any tickets for it, wouldn’t pass a mot though so did have to swap it out for my stock exhaust and swapped it back after.

[@ryanwilkins3206]

if it was cat back why wouldn't it have passed an MOT? MOT doesn't measure for noise yet.

[@poitynine]

@@ryanwilkins3206 Mot does measure for noise. It failed its mot a few months before I traded it in. Failed for a few things including the exhaust. It’s section 8.1. noise “Exhaust noise from the vehicle must not be unreasonably above the noise level you’d expect from a similar vehicle with a standard silencer in average condition.” Mine failed on section 8.1.1.(a) “Exhaust noise levels in excess of those permitted.” Which is a major defect. Had to put the old back box on but didn’t have to put the mid section silencer for it to pass. Just removed it again after it passed the mot.

[@ryanwilkins3206]

⁠@@poityninethat’s really wooly and subjective because there is no definition of what is excessive. My GT86 passed its MOT yesterday with flying colours and she is a lot louder than stock, think she comes in at 92db which is about 15db louder than stock 🤣

[@poitynine]

@@ryanwilkins3206 does urs have a back box? Mine was just 3’ pipe work from the cat to a twin tip exhaust. Mine was 111db which was way above the stock level. The exhaust on my new car passed it’s mot but it’s just a gpf back exhaust from cobra sport with a back box.

So every single custom exhaust shop in the uk is illegal

[@rb-1236]

No. The onus is on the vehicle owner to use the vehicle in an appropriate location based on your modifications. A custom shop can do absolutely anything you want, but that doesn’t mean you have to drive it on a public road.
