1. A method of controlling exhaust gas delivery between two turbochargers, comprising the steps of:
releasably connecting a first exhaust conduit to an exhaust manifold of an internal combustion engine and to a first turbocharger;
releasably connecting a bridge conduit to an outlet of the first turbocharger;
releasably connecting a second exhaust conduit to a second turbocharger, the second exhaust conduit intersects the first exhaust conduit;
delivering an exhaust gas to the first turbocharger through the first exhaust conduit;
delivering the exhaust gas from the outlet of the first turbocharger to the second turbocharger through the bridge conduit;
sensing a predefined operating speed of the first turbocharger with a sensor; and,
opening a valve to allow at least some of the exhaust gas from the first exhaust conduit to bypass the first turbocharger through the second exhaust conduit and delivering the bypassing exhaust gas to the second turbocharger in response to sensing the first turbocharger reached the predefined operating speed.
