Sorry to hear about that but will be good to catch up anyway. Tbh I've never run mine open, far to paranoid about a stone or something finding its way in especially since i don't have a under tray any more! But now you said that it is quite tempting haha But yeah mpg is great, mid to high 30's easily but i think my thermostat is sticking a bit as mine seems to run cold at times and goes on to cold idle and uses a bit more fuel at times Can't say mine uses any oil though, never had to top mine up between services or anything :s The downpipe isn't too bad considering how low it sits, i can still get my cusco lower brace on if i wanted but then i catch that on everything so haven't used it, my main issues atm seem to be the engine mounts being a bit soft. (age related i guess) so need to get new ones but being one is custom it makes it a bit of a ball ache! Getting tempted to buy a set of levin mounts and re-do mine as they are 22 year old corolla gti mounts and the design of mounts has improved greatly over this type. It probably doesn't help that im not using the front or lower torque mounts either, im just relying on the poly filled starlet mount on the back lol
