tubular exhaust manifold. Instead I'm getting a custom made tubular exhaust manifold that will be terminated to work with my new turbo. It will mate to the turbo via Tial's V band design.

Now I've decided to go bigger to the GT28RS with the Tial V band system. Opting for this reduces the turbo's weight by 33%! The Tial cast housing is made of stainless steel material that is polished to a smooth finish on the inside for better flow. I decided to go with the Tial housing that provides an A/R of .64.

Also I'm seriously looking at modifying the centre cartridge or steel ball bearings by one made of ceramic material for even faster spool ups.
