2) APS 321 SS Twin scroll headers - $795

3) APS cold air intake system with 65 or 80 mm MAF - $495

Total - $4685

The APS TSR 70 turbo with the larger .82 A/R twin scroll turbine housing produces 19.21 PSI at 3500 rpm approx.

The higher boost at 3500 RPM that David mentioned at SEMA (21 PSI) was generated by utlising a smaller .63 A/R twin scroll housing on the TSR 70 turbo though APS engineers decided to specify the larger .82 A/R twin scroll turbine housing to ensure plenty of high rpm power for the STI engine, hope that helps.
