Yeap, secondary cats are gone. I gotta pick up all my video/timing gear from Stoke the weekend before. The torque curve is less "vertical" from 2500-3000rpm than my old RS6 and more gentle so instead of one almighty shove you get a constant surge which keeps pushing harder and harder until it levels out at around 5000rpm and slowly dies off. The power also levels out at that rpm roughly so it would need better turbos for more top end power
