Anyone just install a set of Corsa 300 cell cats on stock NPP exhaust?
If so what was the sound difference and did you have any CELs?

Thanks

The biggest difference I find with sport cats only is the cold start. It is much louder and almost has a hollow snap to it. Easily 20% louder. It can set off car alarms. On the move under load I'd say they are about 10% louder in all modes. Same general character just a bit louder. It also seems to me that the pops on upshift are a little more frequent with them but that could be my imagination.

Not your imagination, I have a Corsa Cat Back and you are right on with the sounding percentage and there is more popping in between the shifting.
