ok...i know drive pressure is the pressure in teh exhaust manifold...but...what does it hurt other than having exhaust back pressure...and dont you have to have it in order to have boost and drive the turbo...which brings me to another question...if there is 50+ psi in the manifold b/c of the turbo restricting flow...then why does it matter if you have 4" exhaust...
im jsut needing edjucated on drive pressure more or less...thanks for your time
