I was quoting you Chris on the DMS / don't bother decatting comment ;-)
I'd be very cautious about changing mids and downpipes. The downpipes have a bigger effect on noise (but also on performance) than the mids, but doing both together is, in my opinion, a little too loud and droney for every day use. The secondary cats are in the midpipes, so by definition downpipes don't remove them, only the primary cats. Evolve then code out (no need for any electrical plug-ins) the emissions warning light in their map.
Where abouts in Essex are you?
