Hello, I recently bought a universal performance air filter from the local spares shop (cost £15). I have taken the original air filter out and attached it to the airbox but it hasn't made much of a difference at all to the sound. I was hoping for a nice roar but I don't really get this. Anyone got any idea how i can make it louder? the bloke in the shop said drilling the airbox would make it louder if i wanted. Any suggestions please?
Cheers
