Yep, Steve, that's a fair point. recirculate the stuff rather than vent it. I think that I emanate from a more gentle era where less more.

As far as noise goes, I always thought that the objective was to make as little [noise] as possible but to get useable, driveable performance maximised.

So, screamer pipes have no place in road cars? That's my position.

As for emissions, I cannot comment - I'm lacking a degree in biochemistry, and also lacking one in green ecology!!

The only thing I can see as a problem (I'm not qualified to comment on this either) is that over zealous EGR can increase combustion chamber temperatures and increase NOx emissions.

Perhaps we should all drive 0.8 litre three cylinder cars which attract £0.00 VED.
