Do i have to change the whole exhaust system for MoT?

Every year i change my full system back to the OEM "scud launcher" for the MoT

I got a Hi-level Micron race oval and am contemplating cutting the OEM silencer off to attach it to the micron pipes for the dreaded hour

Can it be done.............has it been done?

I got a db killer from Beowulf which doesn't exactly make mine quiet, but quiet enough that the MOT guy doesn't laugh at me... Or maybe you could find a cheap Micron endcan that'd fit?

Is it worth putting it in for MOT as is?
My Mot did not involve the engine being started, someone else said there's was all of 6 minutes.
Check if you can get a free retest next day or week?

So long as your can does not say "Not for road use", "race use only" etc. There should be no problem. The requirement for a BS or E mark went some time ago.

My local man views a loud can as an important safety feature. So unless yours is extreamly rediculously ear drum bursting loud, just take it in as is.

if you're considering p/x the bike in future an intact OE exhaust can only be a bonus.

Find a more biker-friendly MOT place and leave your micron system on

Yup, but they're still required to not be too noisy... Something along the lines of "no louder than an equivalent vehicle". But it's up to the tester.

Yes, the equivalent requirement. So two full bore SVs attend for an MOT at the same time. Equivalent bikes, none significantly noisier than the other, so both pass.

My local guy is a massive bike fan, the whole test last week took about six minutes, he was sat on the bike for the whole thing.

First he drove the bike up into his test garage, and swiched off the engine, then he swung on the handlebars for a bit to test the steering bearings, then he pushed the front wheel onto some rollers and pressed a button on a kind of dyno machine which started the rollers turning, and he used the brake to stop the wheel and get a reading.
Same again with the back wheel,
Then he pushed it forward further to test the headlight alignment. After that a quick look at the tyres and pushed the bike back to me, and said, oh yes lovely that it I'll just do your paperwork.

I might have missed him doing the odd thing because I was chatting to other bikers who were waiting their turn, but to be honest I wouldn't be too worried, because the test didn't seem to be too rigorous and he certainly didn't get on his hands and knees to look at any exhaust stamps or anything. He didn't try the horn or indicators.

The bloke before me had an ancient triumph 750 bonnie which he had not ridden for 18 months and the exhausts on it were extremely loud, but he passed no bother.

Ash,
try western Spares at Millbridge - he used to be pretty coll regarding a can
