I have to change exhaust

My "not for road use" exhaust has failed its MOT because the examiner said he had no choice but to fail it for that reason. It was all looking so good too then he just happened to notice the stamp on it.
I have the original exhaust so changing over is no problem but will I have to get new gaskets or will I get away with the ones already in it.
Thanks.

get the sand paper and autosol out about an hours work max then it won't say not for blah blah

Put a bit of tape over it. They're not allowed to touch the tape as far as I'm aware.

Otherwise, polish it out.

+1 they cant remove the tape

Bit obvious if you go back with a bit of tape over the stamp they pointed out though? unless your going to go to a different MOT station?

Thats what I was thinkng, and as its a free re-test be best just to swap it over then back again.
I don't want to put it all together only to find it blown because I did'nt use new gaskets but hoping I would get away with it.

There only a few quid anyway so just replace them while you have the exhaust off. Don't replace them again tho if your putting your other pipes straight back on.

change your tester, mine is **** hot on safety related, and thinks a loud can is an essential safety feature

What gasket - for the header pipe?

Is it a full system, or just a slip on?

That's a fair point surely you only need to change your end can that has the stamp on it?
Or as above find a dodgy place where they check to make sure it's road worthy but don't take the wee
