No. But it depends.
It may be possible that it's legal in terms of noise depending on which dB killer/s are installed.
However as your bike now has no cat in the strictly speaking it is illegal.
BUT as of yet there are no emissions checks for motorcycles in the MOT test. So having not having a cat isn't a fail. Being "too loud" is at the discretion of the tester. No dB meters involved.
How much information does your insurer require? Are they covering themselves in case you may want to claim for a full £2000 titanium system? Or because they think its a significant power adder?
Won't "slip-on silencer" satisfy them?

It just a slip on can not a full system but uk insurance will try anything to deny a claim so I want the exhaust to be 100% legal if I ever need to make a claim

 

Currently we are more lax here in the UK regarding motorcycle exhausts than the EU countries so there isn't really much a market for "e" approved exhausts here. Therefore a lack of UK supply.
You find "e approved" compliant silencers on eBay from Arrow and Leo Vince. They are usually from Italian suppliers though, so factor in VAT, import duty and additional courier charges.
They look nicer than the stock silencer and will run cooler but minimal weight or performance benefits over stock.

 

Do you know if any tuning is required after fitting the arrow silencer?. I'm not too fussd with the weight or performance really as the bike has a restricter mapped in because of my a2 license is more for the sound really

 

No tuning should be required for any "e approved" silencer as long as you don't tamper with it.

 

Don't tamper with it? As in don't de-cat it?

 

Or take the dB killer out.

 

I may be dreaming it....but I thought I saw that Arrow exhausts are only compliant with their full system. They have been tested on numerous models and list them so they should have a compliant Arrow. However that then is a major change rather than just a slip on which most insurers don't have concerns about (at this time...watch this space)

I only recall this because I looked at the Arrow as a slip on...and then discounted it and went for the Wings.

Check though because my brain is not what it should be.....

 

I didn’t know much about ‘em as they came with the SMT…..but they sure give off a nice burble and let the other car owners know you’re about…I’m begin to love them

 

Can you just declare it as "not approved"?

When you do a quote online there is an option for that, as well as for "de-cat".

 

I had no problem covering my smcr with a declared Wings box on, either with Bennets or MCE
