What I'm asking is at £1200 is it worth it?
And, if I went with no cat (downpipes for £300) would a tune be needed? Not fussed about the check light as I can reset this. I did run no tune and no cats on the 1M and never had an issue. When I had it on the dyno the afr was absolutely fine.

Fabspeed has posted dynos on 1) a stock exhaust with a stock DP and 2) a stock exhaust with a 200 cell catted HJS DP. The delta is 30+hp and ft-lbs, as I recall. For $1100, that is darn cheap per hp.
