PURPOSE: A parallel double turbocharger device with an integrated gas path, capable of preventing reaction speed delay due to mode conversion is provided to reduce weight by installing a left and a right exhaust line, connected to a primary and a secondary turbo charger, in an engine room without pipe length difference. CONSTITUTION: A parallel double turbocharger device with an integrated gas path comprises a left and a right exhaust line(3,4), a primary turbo charger(1), a secondary turbo charger(2), a primary intake line(10), a secondary intake line(12), a bypass line(14), and an ECU. The secondary intake line, connected to the secondary turbo charger, is branched from the primary intake line. The bypass line which bypasses the secondary turbo charger connects from the secondary intake to the primary intake line again. The primary turbo charger and the secondary turbo charger are installed in parallel on the left exhaust line and the right exhaust line, which are combined through a piston valve(5) and are collected toward a catalytic converter(20). The left exhaust line and the right exhaust line which connect to the primary turbo charger and the secondary turbo charger are installed in an engine room almost without pipe length difference.
