Boyracer is it childish? I'm one and I like to drive fast?

I drive a 1.6 Ford Focus mk1 automatic 2004 zetec hatchback 3dr, petrol, it's good down the small streets like through the streets and town controls nicely around the bends, I don't like it on the motorway it's slow though around their, will a new powerful exghuast make it go faster? And an induction kit? Should I also lower it? My car is very old it's done 174,000 miles, every time I modify it feel as if am wasting money, am 19 and insurence cost me £1000 to renew this year, I don't know what to do? Should I leave all this modifying around? I watch them cars on fast and furious and pretend am one of them lol

You can't modify a car in any way without informing the insurance company… Then they become your ex… Its not just your driving…50% chance it could be the other driver… Either way if your car gets examined. Your insurance company will be made aware any mods… This will be enough for them to cancel your insurance… And as they tell other insurance companies about you… You well may find it impossible to obtain insurance… Here comes the bus
