A stock ITR cat should bolt up, other than that you'll need one that's 17" long.

Unless you have emissions, just get a custom straight pipe. Have one on mine mating a JDM ITR header and OEM US R exhaust...quiet as can be. :-)

That's what it was on my EM1 so it should be the same on yours. If there's any doubt you can temporarily bolt the header on and install the b-pipe and measure the distance between them. It should be 17".
