Change out the cat, it cleans
up lots of offending polutants,
the dirtier the car runs the harder
the cat has to work, and the sooner
it will burn out and stop working.
My cat is shot, I have a 3" ready to
go into a 3" exhaust system, as soon
as I get around to doing it. I know I
won't pass snog until I do this change.
