Awesome, I could only find a couple, one was an Exhaust upgrade but I don't know if it'll give me much more power, I have looked for exhausts and some of them are more about looks than performance but I will keep looking, and the other one was having a look at the ECU and trying to performance chip the Engine, I have no clue about performance chips lol and neither does the Mechanic oops, thanks for your help though much obliged 
I like what you've done with your Micra it looks great, have you done any performance upgrades on it? If so, I'd love to know 
Cheers
