Does de-catting an S3c improve its performance?

[Midge]

I'm thinking of de-catting my S3c in an attempt to improve it's performance. Am I wasting my time/money going along this route with the Ford V6? Are there other reasonably inexpensive options to give it more poke?

I had an S3C and I decatted mine.

It was difficult to tell if it was actually faster, I never did back to back runs on a rolling road or anything.

But it definitely revved much more cleanly and quickly and it sounded far far better - throttle response was transformed.

I got my cat replacement pipes (and a S/S sports system) from Wedge Automotive.

The cats are unlikely to make much difference, if any really as they are pretty big and not that restrictive. There is a theory that the catted cars, which have around 190 ft/Lb of torque versus the uncatted cars giving slightly less at 170 ft/Lb is attributed to the cat. Personally, I think the extra torque is down to little things like no airflow meters on the later cars, which are a bit of a restriction IMO.
It's a tricky question, and one which you will get many varied answers from, good luck!

In one word "NO"

Although I would say it revs easier.

It is cheaper to remove them, then replace them, which is why I removed mine
