And the overall impact of the cat is negligible when the wastegate circuit bypasses the cat. You get the lower dB at cruise and idle as well as cold start without impacting the midrange to high end WOT performance.

This gain is across the whole power band or just peak power? Can you link me to a graph comparing a bell mouth 3" like the invidia to yours?
