I reserve my judgement as I watch the thread with interest.
Real world experience:
Had Jock De-Cated at DP along with a TF straight through pipe. I was happy with performance.
Then Came Bessie, which I think was stock when I acquired it from a stealrship, It had "ROB DOG" (anyone here know him?) stamped on the back window.
I have gone through Bessie front to back and sorted a few issues(leave that for a chat over a fire one trip) front to back and I love the way she drives now.
Now Bessie still has a CAT + BAS 170 + BAS IC with hose + TF straight through pipe and I think the performance is better. I think It might be due to the larger Nugett Stuff intake solution which the car loves. So I am not sure a DE-CAT is worth casing in my case not to mention the smell with the CAT removed.
