3" tailpipe after turbo here, no cats.
The tailpipe quiets it down a lot but does affect spool. When I had the tailpipe off last fall you could definetly notice a performance diffrence.
Spool speed and HP were down noticeably. I would run a 4" with a muffler or resonator or both if you want no restriction and a quiet system.
Maybe a 4" Duramax catback modified would do the trick.

There are two components that impact how effective the turbine works (which in terms obviously impacts the compressor). The temperature differential across the turbine and the pressure differential across the turbine. You want the exhaust gases entering the turbine as fast and as hot as possible for maximum performance. You want to the exhaust on the down side to be as unrestrictive as possible.

Because the turbine is an expansion chamber. The more heat it can extract from the exhaust gases, the quicker and faster the wheel spins.
