If my last mot had an advisory of loud exhaust, is it likely the mot station will fail it this time around or just advise again?
Is there a marking to say silencer are road legal (thye're screamin eagle harley ones?

If it was an advisory last time and they are no louder, it should be the same this time.

DO remember that pipe loudness is in the oppinion of the tester though. I would personally come down hard on harleys with screamin' eagle pipes because they've been taking the piss for far too long while other bikers are penalised or fined for rediculously loud pipes.

The rules state they should be no louder than the standard exhaust on a bike of a similar type.

So you're lucky I'm not an MOT tester because I'd make you either fit a baffle or go home and change them for standard ones to pass the MOT like I've had to do for years with my sportsbikes.

Or you could fit a baffle.

I questioned why I got a advisory on the bike.

Tester said ANY non std exhaust constitutes a advisory now.

Thumbs Up Triumph got an advisory "Exhaust excessively loud" but apparently just because it wasn't standard.

Is there not a new 'rule' in play in regards to exhausts?
I may be wrong, but whilst I was down in Devon I needed an MOT.
I googled a few things - If the exhaust isnt 'E' marked its an instant fail? Im prolly wrong but it did get me thinking.
Spent ages scrubbing out the Not for road use (altho the pipe isnt that loud) - and again, I got an advoisry - which has been the same with all my pipes.

Hi

Lack of marking used to be a fail. They changed it a few years ago to being as quiet as a standard system in reasonable condition in the testers opinion.

All the best

Isn't there something age related as well?

My old Z750LTD was a US import and it had virtually straight through slash cuts on it, which were ridiculously loud at anything over tickover.

When I got it tested, the guy said he couldn't fail it, because it was too old (1980) so he gave me an advisory.

I have an E-Marked aftermarket exhaust, with no baffle.

Didn't get an advisory at all.


What if you was to take up the recent Yamaha offer, and buy an R6/R1 with the Akrapovic exhausts?

Surely if they came from factory, as new, they're standard on that vehicle? Thus allowing all other bikes of type("sports bikes"), the ability to be just as loud?

Strange, mine didn't get an advisory, It is a Triumph exhaust but it's the race can and not exactly quiet Twisted Evil I go the long way to work or back so I can go through a long-ish tunnel Twisted Evil

It should be quiet enough to have the E mark (assuming it is for the silencer, not E marked as something else totally random). In theory the baffles should not be removable (and Akrapovic put a tiny spot weld onto the bolt holding the removable baffle in so it strictly speaking needs to be broken to remove the baffle), so removing it means modifying the exhaust to be noisier. Which is in itself an offence.

Only if the exhaust is road legal, and a dealer selling new bikes fitted with illegal exhausts is on fairly dodgy ground.

Likely the Akrapovic exhausts have a legal baffle fitted or are officially supplied without being fitted to the bike.

Exhaust rules have changed loads over the years and are now hideously complicated while they try to not contradict previous laws. These days (and since the mid 1980s) there are specific limits on how loud the exhausts can be, with standards for how this measured (and not some dodgy check at X rpm with a meter vaguely Y cm from the end of the exhaust). If they are not this quiet then they are not legal, so a noisier exhaust from new just makes the new bike illegal.

That said, construction and use rules are rather different to the MOT rules.

All the best

Keith

I fitted Slash pipes to my XV1100 as the orignal shotguns were rotted when I got the bike. I dont take my bikes to motorcycle dealers but a local garage that mots cars, trucks busses and motorbikes (search yell.co.uk for garages that do this), and the advantage is

A/ you can wait whilst its done (dont have to leave the bike with them)

B/ they tend to love bikes, and are not in the market of wanting to either sell you a new bike or want to repair yours.

when I took my XV1100 in the tester called the manager over to listern to my pipes, not because they were damn loud, but to share the pure joy of a real roar, they loved it, and NO advisory.

This. The Akra will be supplied with the E Marked Baffle fitted. If sir should happen to remove it then the dealer wouldn't know anything about that. Wink

Ducati got around it in a similar way with the 996R etc.

Basically included the race exhaust system and relevent Eprom chip in the box with the bike, but not actually fitted at the point of sale. Laughing

Had an advisory on the Bandit with the Beowulf can last time, even with the baffle fitted.
Will be interesting to find out if it happens again when the next one is due

I fit my baffle for MOT, never had an advisory for it.


My brother doesn't have a baffle for his Muzzy system, he asks the place before he books if they will fail his exhaust on the basis that he will go elsewhere if they will - he hasn't had problems that I am aware of.

Fact is, large engined V-Twins with open pipes sound ace.

R1's with unbaffled Akra's sound unpleasant.

MOT guys know this.

Police know this.

Hence why the harley crowd don't get pulled over or failed.

My bike has sounded biblical for years. Wire wool wedged down the spot with a broom handle... ride to centre gently.

Enjoy pelting people you overtake with crumbling wire wool for weeks after,

Hmmm, as that's an entirely subjective point of view, it's stretching it a bit to label it as 'fact'.

Personally, I'd say the exact opposite from you - doesn't make it a fact, merely a point of view.

I tend to think straight piped cruisers sound like agricultural machinery with blowing exhausts, to each their own of course. I will admit that the triumph cruisers all look and sound rather nice though.


As for the Harley crowd not getting pulled over, could be for one of three reasons:

1 - downright impossible that they are speeding
2 - cops are worried the bike might not start again
3 - cops like their anuses intact
