Message	****New Split Pipe down pipes with waste gate separators for the smaller turbo's**** This is also known as divorced waste gates…. 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 inters 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. By keeping the exhaust in a pipe similar to the exhaust wheel and separating the wastegate you dramatically speed up the velocity of the exhaust gases causing the turbo's to spool about 500 rpm sooner. 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 setup.
