Would a new exhaust system mess up my restriction?

In a way, Yes. The certificate is proof of 33bhp to the police and a court, if it states the bike most remain standard then that is the legal statement of the certificate.

Slip/bolt on cans are not performance enhancing exhausts on an SV.

Going back to my previous thread about having a dyno printout...

The best thing to do is have a certificate and a dyno read out (less than 33bhp), this info came from my neighbour who is a high ranking traffic cop.

Update: You need a certificate to produce to a court!

Not really, all it says is that a restrictor kit was fitted at some point.

What law says you need one?

A pompous legal system in court, not exactly a law we know about but they need a copy for the court record and failure to produce isn't a good option. Paul, my neighbour, has recently been involved in such a case. An R6 owner was caught speeding at 142mph on a restricted licence, they guy removed the restrictor obviously.

But if he could have produced a certificate in that case, then what?

I very much doubt they'd take you to court just over not having a certificate if you've a dyno printout of <33bhp, unless you're caught at +100mph speeds or other such silliness.

No what I am saying is if you ever have to go to court you will need a certificate, the old bill aren't to fussed but you have to produce a certificate to a court!
