As part of a full performance exhaust system on a 180 (Janspeed manifolds and a good cat back), is a Janspeed sports cat worth bothering with?

I'm not interested in a de-cat, to keep it legal.
So this is purely a performance comparison between the Sports cat and the OE cat.

Obviously with the Janspeed manifolds I will have lost the pre-cat already.

I've been warned off by one person who had a sports cat (don't know brand) on a K4 engined car. It went wrong after 1 year and failed the MOT. So there are obviously some sport cats around that are not very durable.

They're not cheap so I'm currently inclined to stick with the OE cat, unless it's REALLY eating power. At least it's durable.
