haha. Yes there are some performance gains to be had. but not on a standard motor! There's heaps more restrictions on the standard micra which hurt performance more than the catalytic converter.

what tom is saying is that doing one thing and not all the other things won't actually be much use. (don't do half a job)

DO THIS>>>http://www.micra.com.au/technical-articles/1500powerup.php
($1500.00 power up)

This is esentially...

1- custom cold air intake (your own design, this is fun to try different things out to achieve the best high/cold air flow)

2- extractors (mine are 4-1 but some ppl have gone for 4-2-1),

3- lose the first cat,

4- 2" pipe thru to high flow cat and back box.

this should cost less then a grand, so that in your money is bugger all
