PSE and insurance

[Azura_tzo]

For the people who have fitted this after market, how has it impacted on your insurance premiums?

I am thinking of getting one fitted. Direct line (current insurers) say it is a +25% impact on my annual premium!! It is classed as a performance upgrade, although it does not increase BHP. This category covers "performance modifications" that impact on the standard BHP by up to 10%.

Seems harsh!
