Are there aftermarket shifter cables available for the TSX?

I am in the process up upgrading all parts relating to the clutch + shifter on my K24A2 2004 TSX 6MT. The master/slave, shifter assembly, base bushings, cable bushings, detent and shifter springs have all been upgraded with performance parts. Now I need a pair of Street or Race Spec shifter cables. What options if any are available for the TSX? I find it hard to believe that Honda OEM would be my only option since so many parts are interchangeable between the TSX/Accord/RSX/Civic si.

Thanks!
