They are different than J/ramK. The left side collector tubes are very similar but the main tube is notably wider diameter and a little shorter so that it doesn’t appear that it would snake down past the torsion bar (F/G also longer wheel base than J/ram K of course). The right side has more apparent differences in the casting from J/ram K with the combined tubes for #2,#4,#6 exhaust ports.
