Stubby cans/MOT requirements

[carlosthejack...]

Just a query about stubby/race/GP cans and the requirements for an aftermarket can to be BSAU stamped in order for it to pass an MOT. I'm looking at getting a stubby for the Hornet. Now I've seen a few that are advertised as "not road legal", but come with a baffle to kill some noise. I was wondering if anyone knew what MOT requirements are for a can to have the BSAU stamp? Will a can without it pass the MOT as long as it's not stamped "not for road use" and comes under the DB limit with the baffle in? I did hear it's "at the MOT'rs discretion".

Would I be as well just putting the stock can back on for the MOT and then swapping it back once it's passed, just to be on the safe side?

This is the one I'm looking at: https://www.pipewerx.com/pipewerx_bikes/products/pipe-werx-sl-gp3/honda/cb-600-hornet-03-06/honda-cb-600-hornet-03-06-stainless-steel-round-gp3-race-exhaust.html

Reason for rejection


3. A silencer marked 'NOT FOR ROAD USE', TRACK USE ONLY' or similar words.

Hi

MOT rules are that it must not be stamped "not for road use" or equivalent, and must be as quiet as a standard system in reasonable condition in the opinion of the tester.

Which is different to requirements for it to be road legal.

All the best

Awesome. So if it's not stamped at all, and is under the DB limit, it's down to the testers discretion? Okie-dokie!

That's about it. The tester has to be satisfied that the exhaust makes no more noise than the standard system in good condition. That kinda rules out all 'race' cans, going by the rules. Of course, if it came to it the tester would simply say it had a different silencer fitted when he tested it.

Hi

Yes, but if it is a stubby can then it is almost certainly well above the noise limit, so you are dependent on the deafness of the tester.

If you want a cure for insomnia here is some of the legislation on exhaust noise. The clause Every exhaust system and silencer shall be maintained in good and efficient working order and shall not be altered so as to increase the noise made by the escape of exhaust gases would seem to make any exhaust noisier than standard illegal (even if quieter than the legal limit).

All the best

I wonder how they will view my home-made exhaust? IT's definately 'standard' for the system

Pipewerx cans are awesome m8, if you are worried about the GP3 not being legal then do what I did for my review and ask them for a legal version with wide outlet, if you get the DB killer from them it should keep it within reasonable levels regardless and without they sound wicked!

Its a touch bigger than stubby, sounds figgin awesome and 100% legal, FWIW I dont think the Pipewerx race cans are stamped as Not For Road Use but it is worth asking them.

Also, they can be a PITA to get an email back from this time of year, best calling them

Don't worry about it.

I've had about 3 bikes MOT'd with loud cans, didn't even bother to put the baffle in and they've all passed.

Get 'em to stick the wide outlet on it - it looks mint!

Great choice BTW

Carlos, I don't live too far from you and my tester calls loud cans a safety feature... Should see the one on his B12 bandit

[Paulington]

I had a carbon Pipe Werx endcan on the SV650S, absolutely fantastic, can't rate them highly enough. !

When it came to the MOT for my bike, it's got a full race system on it. The tester just asks I show him that I have the standard system, since I do he fails it, then passes it an couple of hours later so should anything happen he can say I brought it back with the standard exhaust on. That's what he says at least.

Take it to a Harley MOT tester, I'm sure they wont have a problem with the noise level

[Sako]

never had a noise issue with MOT, had 1 fail due to can stating 'not for road use', but can(s) i have fitted since have no markings and passed fine.

[Louise]

Had MoToGP stubby on the Zx636 one Mot just issues noisey exhaust. One I had on the R1 wasnt too noisy but did have stamped 'not for road use' so spent hour or so rubbing it off... again pased with noisey exhaust
Pipe dose look mint tho, did look into them before the MotoGp one.
