Mot question - exhaust exit point

[Kieran]

A mate has built a Nova kit car (think pink panther mobile, but blue), very cool and fitted with a 1700 Alfa flat 4.

It has been off road many years but he's finally getting round to finishing it for his impending wedding.

He had a set of custom exhausts made that exit through the rear wings.

He has had a mix of comments, some saying it will never pass an mot with them how they are.

I know some testers frequent this manor, so I said I'd ask for opinions here.

Here are the beasts



Comments?

[hairymel]

not a tester, but the only possible thing that springs to mind is

7.1.5 5. An exhaust tailpipe positioned so that fumes are likely to enter the drivers or passenger area.

don't think anything else covers it

[Rich]

As per what hairymel said, have you actually checked the MOT guidelines as posted by myself?
Shouldn't be an issue. Many vehicles have side exit exhausts.

[mk2cossie]

Theres a whole load of exhaust stuff changed in the last 3-4 years on the mot.
As above, only really an issue if the gases are likely to get in the cabin or its too noisy

[hairymel]

or if it sets fire to the glassfibre body while its being tested

Exhaust fumes don't enter the drivers cabin, pipe doesn't pose a danger to pedestrians so that's a pass.
As for noise levels that's entirely down to the tester.

I am no mot tester, but reckon it would fail. The fact that you say it exits from both rear guards is the problem. The fact that it looks like it's directed upward also looks like a problem. Very dependant on the Mot tester ,however ,the fact that it's going to blow hot exhaust gas face height to a child on the pavement ,or someone on a disability scooter/ wheelchair, doesn't bode well. If it was only on the right rear ,I think you would have got away with it.Look at most super bikes. Can't be a styling thing only that if the can faces upwards,they always have a tailpipe angling down again. 

Let us know the outcome,would be interested to know.

Great. I don't think there is anything in the testing manual, which once again I will point out is in the public domain, which applies an RFR for 'may warm a child's face'

[Rich]

Have actually consulted an MOT tester and looked at the manual, together, there is not a specific RFR we can find based on location alone. So there you go. It's fine. Now go gas a bus stop full of nuns with it. Because it's awesome

Seeing this Nanny state has gone ridiculous over Elf and Safe Tea, I for one wouldn't be putting money on an exhaust like that passing a mot,just because the rule book doesn't state " May warm a child's face". It's called common sense, a very rare commodity these days....

Sadly common sense isn't how an MOT test works. A tester cannot invent an RFR because he doesn't think something is safe or sensible if it falls within the rules. All he can do is add an advisory notice to the paperwork to show (to DVSA and the owner) that he is aware of it. He can even mark it dangerous if he likes but that isn't a fail.

I was only trying to be light hearted with my comment.

[Kieran]

Bike exhausts can be angled anywhere, usually upwards or under seat.

'Exhaust may warm child's face' is the best mot advisory ever. I hope it happens!

[Kieran]

I guess standard exhausts should be advised

'exhausts may warm nuns and kittens ankles'

[Deleted]

Not taking you to task Rich. Just making a comment. I think it's cool and I hope it does pass. Problem is it is a bit open to wether the Mot man is on your side or not. I think it does say somewhere that side exhausts must exit behind the front wheel. So,FairPlay,no stubby screamer poking out just behind the front bumper. So, here's the bit that's open to debate. It says behind the front wheel. If the guy is a curse word,he could theoretically argue the toss that it doesn't say behind the rear wheel......and that's where the fun starts

As a total aside,I knew guys 25 years ago ,whose fathers raced V8 sprint cars on a dirt oval. Like midgets just bigger. Don't know the correct class,terminology,but that's besides the point. They really used to,shall we say,make full use of the rule book. As for exhausts they first changed them to run the full length of the car,rear exit. Nobody complained. Next up subtle change that exhausts terminated at driver eye level. Nobody complained. Then,introduced a bit of wire welded in right at the end of the exhaust,thin enough to burn away during a race,leaving no trace. Nobody knew and nobody complained. Come a big international event with visiting teams from the states,they strung mothballs on the wires. Made whoever was behind them,eyes water like curse word,so much so they wouldn't stay close enough to overtake. All sorts of threats and aligations,but come the end of the race they had won and no evidence to prove otherwise...

Threat hijack over. Would like to hear from OP if it does pass as is.

Best advisory

[Kieran]

A close 2nd

[wildy]

Fumes into the cabin is only an RFR for class5.

On Class 5 vehicles only, check that exhaust
fumes are not entering the driver’s or
passenger area.

i've had a fail on exhaust fumes entering car, think that was due to no floor!!!! lol

Comments?

If they were in lower part of panel, i.e. pointing downward don't think anybody would mind/notice. Just look a bit odd as if something is missing like a petrol cap or similar.

Just asking to be used as a funnel for a litre of bubble mix to see what would happen. Or "confetti - or rice" topical suggestions. Although not sure all three at once would work as expected....

As well as the cans and boots trailing from it I can imagine a load of - merry souls - thinking of great things to do with those come the happy day.

Suggestions for what empty bottles would be best suited found sticking out of them?

I think if you do something that .... well lets say ....original - you deserve everything......original that follows

I vote for bubble mix, banana's and condoms...... although a couple of kilo of flour would be a laugh as well and cheap.
