my uk97 more power
 

hi guys
i have a uk my97 late spec,with central coil ignition pack,i have a kn panel filter and a magnex back box looking to add the centre pipe as well.
at the moment it is producing 243bhp.
i would like it to be closer to 280-300 bhp.what would be the best route to go,taking in hand everyday practicality in driving the car.
all positive advice welcome.
cheers
