Abstract
An exhaust system structure includes an exhaust manifold discharging exhaust gas through at least one runner towards an exhaust pipe. A front pipe is connected to a front end of the exhaust pipe. A collector connects the at least one runner and the front pipe. The collector comprises at least one inlet communicating with an exit of the at least one runner. An outlet communicates with the front pipe such that the outlet discharges the exhaust gas into the front pipe through the at least one inlet. An extended portion has a radius greater than or equal to that of the exit of the at least one runner.
