insurance - s2 exhaust + pipercross induction kit

question - have informed the insurance company about the stage 2 exhaust and pipercross induction kit i have had fitted to the car - told them that the power increase was “negligible” - which imho it is. Does anyone have the official power increase that either of these mods causes?

Also, a removeable steering wheel does NOT reduce my premium, which i thought was a little cheeky.

I always play it safe with the insurance companies. They are just looking for a reason not to pay out. I just take the hit, most insurance companies have a less than 10% power increase as there standard for zausts etc.
