ABSTRACT:
This invention relates to a dual-exhaust system for an internal combustion automotive engine. Instead of just the usual direct channeling of exhaust gases from the engine towards the muffler, the system of the invention also couples the exhaust flow from one pipe to the other, and vice versa, mixing and equalizing the pressures in the two pipes, by the addition of two further pipes connected between the first two in an X-configuration.
