I'd also leave the regular cat on and replace the precats with MSDS headers. Much better for power gains than the other way round.
And yes, I did misread your Cougar mpg comment

Soz!
No worry's mate

we all do it at time's

.
But mate i am wrong in assuming the PRE cat's are not really restritive as the main one is????
I was gonna take all 3 of mine and then whip the main on for the MOT,Naughty i know but never did do that
I miss the V6 raw they just bore me after 100mph slow as,Or it seem's now having a turbo car one been a cossie and my S1 everything else seem's slow now
Although be it the V6 is better round town for blast as the power is just there

Sod i am gonna go buy a cougar again

lol
