MOT Regulations (exhaust) help??

11th June 2009, 21:55

i am a bit puzzeled.
i had my MOT today, and it failed on the exhaust, so i was going to buy a sportex 3' backbox.
but the MOT tester said if i do that, and is louder than the standard exhaust, it will fail on new regulations. is this true? i did a quick search on this but i came up with nothing.
i see loads of cars with stupidly loud exhausts but how do these pass the MOT?
i dont no what to do, i dont want to buy a standard one to pass the MOT, and then buy the one i want.
suggestions?

not sure mate but i know regs are getting alot tighter these days, but unless your new system breaks the db limit i dont see the prob, check with the distributor before hand or bodge your exhaust till you pass the mot, better yet borrow someone lese backbox, there will be hundreds of ppl on here with there standard in the garage

ye they are, it sucks ass.
its so stupid.
i think i am going to phone my tester in the morning, and ask how loud it can be, then phone/e-mail the exhaust company (sportex) see if at would be MOT passable.
are sportex 3' back boxes loud?
cheers for reply mate.

Mine is only loud at lower revs mate and tbh i know a lot louder systems which have passed so dont worry. Sportex 3" outward rolled sound really nice

11th June 2009, 22:34

Doesnt matter mate, as long as its not antisocially loud, he cant fail it

i dont want to buy this sportex one tho, and end up having it fail the MOT again.
i think i will phone them in the morning and get all the details i need for it to pass.
do you rekon a 3' sportex back box would pass?

11th June 2009, 22:54

my mates garage does MOT's and has no way of checking the db's from a car exhaust!!!

Hes talking rubbish mate

he sounds a bit of a d**k. i didnt take my car for MOT, i cant drive at the moment, (doctors orders) hurt my knee playing football.
i just dont want to spend the money on it, then on the chance, he might fail it.

+1 on that one mate

11th June 2009, 23:04

well new guidelines are that the noise level is comparable to a similar car regularly maintained which basically interprets as standard noise level only

so you saying that only my standard is exhaust is goin to pass?
do they mean noise level when the car is bein driven, or stationary?

11th June 2009, 23:10

Had my VTR done about 2 weeks ago, didnt test exhaust DB

And it doesnt say that in the things to check?

i am still stuck, i will sort something out with him tomoro.
cheers for all the help guys

11th June 2009, 23:12

its noise at idle 450-1500rpm and fast idle 2500-3000rpm and the new guidelines you dont need a DB meter you have to use testers discretion and compare it how loud a similar car is with standard system is

When was this implemented?

Still just does the fast idle, and natural idle were i work, with jsut a exhaust probe and engine temp sensor.

No DB, mine was pretty loud, didnt even mention it

o right. and thats for definite?
to be honest i think the MOT tester being a d**k and any exhaust bar a standard one he is going to fail.
cheers mate

11th June 2009, 23:22

sorry if you carnt post ebay links.

your best bet is to go into regional section and see if anyone is willing to lend you a standard 1.0 bb

what exactly did it fail you on - noise level?

11th June 2009, 23:29

"unreasonably above the level of standard"

Sounds like if you have a de-catted SS straight through then yeah, your fooked.

But just a backbox shouldnt make it "Unresonably" loud imo

i have a standard one on there at the moment.
and it is leaking and stuff.
i was changing my exhaust anyway, but dont want to pay for a standard one, and then the sportex one.

11th June 2009, 23:34

just get a cheap exhaust or borrow one for the test then you dont have to worry about it plus it looks good in the testers eyes if youve done something about it

11th June 2009, 23:35

We failed a car for being 'excessively noisey' before. A pug 306 diesel with a huge japcan and some cone filter. As long as its not absolutely rediculous though most testers wont mention it imo.

Exactly what i said, just some of these straight through de-catted race systems with jap cans are just rediculous.

ye lol
a decatted car wont pass the MOT anyway will it?
so a 3" sportex would be ok, do you rekon?
cos i need to buy the exhaust today, and fit as soon as.

12th June 2009, 09:23

Sounds like the guy testing your car is a tool. should only fail on emissions not noise. unless you have a quad exit custom jap cans or some crap like that.

there is new regulations for noise now aint there.
have a look at the first post on page 2.
it's all on there.

12th June 2009, 09:31

Dont think any of you understand:

"its to the discretion of the MOT tester if he passes/fails your vehicle on exhaust noise"

Your MOT tester is being a cock so he is going to fail any other backbox other than standard.

This rule has always been there iirc but never really used until lately (last month or two).

In future i would ask the MOT tester before you book it in if he'll fail it on the exhaust noise. Most likely say no to get the cash off you.

12th June 2009, 09:37

Sounds to me like the tester is just trying to tap you up for business. Sounds like a bit of an arse tbh.

Just bought a standard exhaust :-(
soon as i get the money then, it coming off. and sportex one going on. then i will always have a spare to put on, for the next MOT, just incase this occurs again.
and yes he is being a cock.
cheers for all the help lads.

12th June 2009, 09:46

NP,

Personally i wouldn't go back to that garage mate, try ask around your friends see if any know any decent MOT testers for next year

And ask before you book it in next time just say something like

"I've got a none-standard backbox on atm, its not too loud but its above standard noise. Would you fail it on this?"

Glad you're sorted now

ye good point.
i will

13th June 2009, 14:32

Had my s16 in for test this morning.
Got standerd centre and scorpion back box.
Passed not a problem
spoke to tester who confirmed he looks more at integrity of system, joints etc rather than noise level.
Said he wouldnt fail a zorst just for the noise level.

13th June 2009, 17:24

This is from the MOT hand book as a “Reason For Rejection” (reason to fail)

“a silencer in such condition, or of such a type, that the noise emitted from the vehicle is clearly unreasonably above the level expected from a similar vehicle with a silencer in average condition.”

PS: You will also fail if the exhaust protrudes beyond the bumper

13th June 2009, 17:41

See when you test something like that in a garage the sound echo's which makes it seem louder

13th June 2009, 20:33

theres no equiptment used for MOT regulations that measures noise levels, as long as its not blowing or insecure or rediculously loud then id pass it. I am an MOT tester

see why cant i have an MOT tester like you lol
all sorted now though, just bought a standard one, cheapest i could find, fitted it, and then going to fit a sportex one soon.
cheers for the help!!!!!

13th June 2009, 22:39

I've heard a few times that if the exhaust is louder than standard then it will fail.

It depends on the garage / tester..

However the above statement is essentially true..

If its not standard in terms of noise (asthetics doesnt matter) then they can fail it..
