Could you give a little more detail on the Sport Cat? I'm wondering if you're having a little bit of trouble with a restriction there. I'd expect more as well.

This is what I have fitted:

Ohh snap didn't even pay attention to the fact that OP was in EU. Ok, so minus about 30-40 whp. Where's all the torque loss coming from? Even if the EU cars are a bit weaker, that car should have still made closer to 450+ WTQ right, instead of the 398ish?

EU cars have more filters in the exhaust too, so could be from that.

I've only had the Sports Cat fitted - the rest of the exhaust is standard apart from having some padding etc removed from the backbox last year to improve the sound.

Your problem is the OPF since you keep the stock exhaust. There is your restriction comparing to US cars
