Very interesting. Mazda skyactive engines have revised chassis tunnels to accomodate long headers. Its supposed to keep hot exhaust gas reversion from messing up the high compression. Yeah, why not do to the exhaust what they do upstream in the intake with valving. There seems to be some issues with the valving being robust enough on both ends with some diesel makes. Would an exhaust valve introduce too much drag in this example?
