There's definitely power gain if you look at the pic of the inside of the secondary cat and see the restriction.... The question is how much??? To be honest, the car seemed to pull good and strong when I did this and at the time is was combined with an Eisenmann Sport. But measurable power increase was probably minimal. Sound was greatly improved. The main restriction in our systems is the primary cat though. That's the key to increasing power, doing something about the OEM primary.
