The wastegate separator bolts to the down pipe and fits in the turbo exhaust housing
creating a perfect circle for the exhaust to exit like an external wastegate turbo. 


The reason this type of down pipe works better is because the exhaust coming off the turbo wheel
 is spinning extremely fast and whipping in a circle.  If the exhaust comes off the turbo wheel and enters
a much larger area it becomes more turbulent, slowing the exhaust velocity; also when the 
wastegate opens, the two turbulent exhaust gases fight each other causing more turbulence.
