Would changing to a Scoobysport exhaust and Ramair (or similar) filter have the same kind of effect on the power output of my 98 WRX as it would on a UK model? Has anyone tried this? Much as I thought it would never happen, I'm hankering for a little more power!!!

A mate of mine has just got a Griff 500 and I think once he learns to drive it I could be in serious trouble (except in the wet obviously!). Sorry I couldn't come up with a less boy-racery reason for wanting more grunt but there we are!

Try http://www.users.globalnet.co.uk/~strong/car/dyno/

this has rolling road data for a load of cars, UK, WRX, STi etc, most fitted with Scoobysport stuff.
