Re: [doc] Cat replacement / Lambda-sensor

[Martin Gutkowski <webmaster@xxxx>]

The engine will breathe a bit more easily so you might get some popping 
from the exhaust as it'll be running slightly more lean, though int 
heory the lambda system should itself correct this, though its ability 
to adjust mixture is very limited.

The lambda system is essential if the exhaust has a cat, but you can run 
a lambda system without a cat - it's just a bit of a waste trying to 
control the emissions to that extent, but then not scrubbing the exhaust!!
