Hi,

This is the mod for changing the colour of your exhaust fumes,
you can have the colours: Purple, Blue, Red, Yellow and Grey/White.
You also have H2O. You know: Hydrogen.

Installation:
First copy the files in this zip to a folder. (you knew that ofcourse)
To install this mod, you have to open the particle.cfg in your data 
folder. Then search for the line: EXHAUST_FUMES. If i'm correct there
are two EXHAUST_FUMES lines. Take the one below.
Delete the EXHAUST_FUMES line below, and change it to one of the 
EXHAUST_FUMES lines in the zip.
If you done correctly, you can play with different Exhaust fume 
colours.


Smoke Increase:
If you want more smoke coming out of you exhausts, you should make
some changes in the lines. 
In every line (except the Grey/White line) is a number 20. If you 
change it to 10 for example, you will get more smoke. If you change it
to 30 for example, you will have less smoke. 
Warning: You can change it to 0 but not more, so you can't change it
to -2 or -3 etc. I don't know what will happen, and i'm not responsible
for any damage.
But if you do it all correct, you wont have any damage. 

HAVE FUN!
