Sports-cat exhaust


Recommended Posts

Calling anyone with a sports-cat fitted to their exhaust system...

To what extent, if any, does the catalyst reduce exhaust smells? I'm fed up of ending up stinking any time I go near the car, and will gladly accept a performance hit for a noticeable reduction in pong!

Thanks in anticipation.

Morning Rich,

Are you thinking from a potential heat-generated by the cat point of view?

I'm not overly concerned about the mixture - It probably does run a bit rich on cold startup, but is fine once up to temp (running omex 600 fuel injection with oxygen sensor).

Anyway, let's not get bogged down with specifics....hypothetically speaking, does a catalyst reduce smells or is it just taking care of invisible atoms and molecules?
