You need exhaust energy / velocity to spool up the turbocharger. Shorter primaries will give quickest spool. That's why Porsche only twin turbocharge since the 993TT, and use very short headers to maximise responsiveness and low down torque. Long gone are the days of using long headers for street turbo's.
