Compatibility issues

[-Vtec-]

hi, I'm new to the forums and i just bought a K&N typhoon CAI, skunk2 catback and OBX headers for the TSX in-which i have a Accord Euro CL9 (Australia) the catback fit but the bottom screw on the manifold that meets the engine isn't lining up right and may need to be drilled out, i was wondering if this is a compatibility issue between the two engines of is the headers just been drilled wrong.
thanks.

and also another question is the tsx's engine mounted differently to the Accord Euro or are they mounted on the same side
