For that power level, you don't need a tubular mani anymore, the FP cast mani and a Mitsu style turbine housing will do the trick with more reliability and less underhood heat. I was just having a few beers with Mike Rizzotti this week and he sold off his Shearer top mount and went back to the FP mani. He's still looking for around 600whp detuned.
