03 LeMans Header Pipes & Crossover

Damn, you're right. I forgot to square it. Which explains why I'm a lowly tech instead of an ingrownear, I mean, engineer.

Aha, I stumbled across a source in the USA for the cross over. With a price even! And they are 42.5mm which is too small for the Sport models.

would it not make more sense for the crossover to cross rather than to do a loop back kinda thing? ie. An X rather than a U or H shape.

It would mean more tubing, but common sense would suggest a better flow.

Of course in the physics of engine design, common sense can be deceiving. example smaller valves can equal more power.
