hrmmm for me.... using the stock wheels and a gps speedo, at gps 110km/hr the speedo reads 113. using bigger wheels, speedo reads 106 at gps 110 . bigger tyres are 205/35/18. stock wheels are what ever comes standard on a Yr 1.3

and using the bigger wheels I couldn't get to the same high speed as the stock wheels on the same bit of road on the same night. I wasn't using the gps speedo tho

also. IMO.. 2inch is 'big' exhuast for 1.3L usually for a 1.8 or 2L NA motor. But if it feels like a difference. it makes a difference :)

hrmmm. do u have a cold air intake/pipe going to your airfilter? I"m not sure what comes with the short air ram kits. Maybe the radiator has more heat blowing over the air filter?? eh?
