I'm not sure, but most likely not. I say this because the probe and MX6 do share an engine and many parts, but im worried about the routing under the engine that goes from the headers through to the muffler. I don't know if the cat or any of those components are in the same place. BUT if you're looking to save some money, your best bet is to buy a quality muffler that you like, then take that to a muffler shop and say that you need the section of pipe from the catalytic converter to the muffler and you need it all installed too. Mine was a muffler, catalytic converter, and pipe, all installed for like 350. I say this because my catalytic converter that I bought the first time didn't really fit, so I wasted 50 bucks. But overall, had I done research the first time, it would've just cost 300 even. Hope this helps. PM me if u need anything else.
