I'm sure there are a bunch of places, try getting in touch with SQC (Subaru Queens Club). They could probably help you find some places in the city. As for elsewhere, you could always try Z1 out in Long Island or Rallispec in South Jersey, ILP out in PA, Pruven Performance up in CT, Nino's Auto Accessories down in Brick, NJ. Also, there's a gentleman named Eric who goes by WRBLUEWAGON on nasioc.com that does installs. He's a Vishnu installer and does very good work. I had him do my uppipe and turboback and help me with my coilover installs. He's much cheaper than most shops. Tell him Calvin sent ya. Also, there's AZP installs. . .bunch of guys from the NYC area that do installs. You can search for them in the Tri-State forum on nasioc.com.
