Optimizing for the torque peak provides the ideal primary pipe diameter, and since peak power is usually no more than 1,500 to 1,750 rpm above the torque peak, the selected pipe size has no trouble accommodating an exhaust volume that essentially flatlines, and then begins to fade rapidly. List of all Volvo S60 (2000 to 2009) and V70 (2000 to 2007) bolts and nuts tightening torque specifications. So you build in a restriction in the exhaust system (either a Anti-reversion deal) or a pipe that makes it harder for the gas to flow back towards the combustion chamber and you make more BMEP/torque/HP when the real deal was a Anti-reversion device with a bigger tube header would have done the same thing or a different camshaft profile. Backpressure: Friend or Foe? Backpressure can influence in 2 places. But it's more than our broad range of sizes. for the power you're putting out, dual 2 1/2" pipes seem to be optimal, you don't lose that much low end torque and you gain good hp at high rpms.
