If there's enough clearance for the dual exhaust, just leave the filter in its original location and tweak the plumbing of the flex lines to clear the dual pipes. As long as the filter stays mounted to the engine, flex lines aren't needed- - - -do the plumbing with 1/4" or 5/16" hard tubing instead. You might need to use longer U bolts on the intake and add a spacer between the filter housing and the manifold.
