For 1, I don't think you'll be able to fit TWO 2.5" pipes in the space provided. 2, I don't think a 2.5L or a 3L could use the airflow capabilities that TWO 2.5" pipes provides. I think it'd slow the exhaust gasses down.
Sorry...didn't mean to hijack this thread.

PM Brad Noon and see what he says.
BTW, Mandrel bent true duals = a great idea. Props to you, Moose.
