Differential leak

[Nicg90]

Hey guys I had a tomei 2-way differential installed by TF Works and now it leaks. I assumed it would be the main cover so I removed it and used rtv to re seal it. Put the cover back on and installed it. Less than 2 days later still leaks. Look underneath and my exhaust has diff fluid on it underneath the driver side axle. I also noticed that it has sprayed up onto the floor of the trunk. Which leads me to believe its an axel seal. Is that possible? Where can I order a new one? Thank you.

I don't know for sure, but I would definitely get some OEM seals and see if they fit. All of those housings are based on the R200 diff, and no matter what, they have to fit the axles in these cars.
