An exhaust management system for use in a motor vehicle having a muffler with a noise-reduction portion, the muffler coupled with a tail pipe (22, 22A) for use with a combustion engine generating an exhaust, the system comprising: a bypass channel configured to be mounted to bypass the muffler, the bypass channel being an unmuffled pipe configured to allow flow of exhaust from the combustion engine; a valve configured for controlling exhaust flow through the bypass channel; and a controller operably coupled with the valve, the controller being configured to be switchable between at least two modes, the at least two modes comprising: a static mode that controls valve movement between a plurality of positions including an substantially completely open, a closed and a partly open/close position in response to user selection and independently of any dynamic parameters of the motor vehicle; and a dynamic mode in which the valve is movable in response to at least one dynamic parameter of the motor vehicle, the controller being configured to control the movement of the valve about a plurality of positions including and between an open mode and a closed mode as a function of the at least one dynamic parameter of the motor vehicle when in the dynamic mode, the controller configured to permit the valve to be in a position that is at least partly open at certain times when in the dynamic mode; the bypass channel configured to increase loudness of sound from the tail pipe (22, 22A) as the valve allows exhaust flow to bypass the noise-reduction portion of the muffler through the bypass channel. a bypass channel configured to be mounted to bypass the muffler, the bypass channel being an unmuffled pipe configured to allow flow of exhaust from the combustion engine; a valve configured for controlling exhaust flow through the bypass channel; and a controller operably coupled with the valve, the controller being configured to be switchable between at least two modes, the at least two modes comprising: a static mode that controls valve movement between a plurality of positions including an substantially completely open, a closed and a partly open/close position in response to user selection and independently of any dynamic parameters of the motor vehicle; and a dynamic mode in which the valve is movable in response to at least one dynamic parameter of the motor vehicle, the controller being configured to control the movement of the valve about a plurality of positions including and between an open mode and a closed mode as a function of the at least one dynamic parameter of the motor vehicle when in the dynamic mode, the controller configured to permit the valve to be in a position that is at least partly open at certain times when in the dynamic mode; the bypass channel configured to increase loudness of sound from the tail pipe (22, 22A) as the valve allows exhaust flow to bypass the noise-reduction portion of the muffler through the bypass channel. a static mode that controls valve movement between a plurality of positions including an substantially completely open, a closed and a partly open/close position in response to user selection and independently of any dynamic parameters of the motor vehicle; and a dynamic mode in which the valve is movable in response to at least one dynamic parameter of the motor vehicle, the controller being configured to control the movement of the valve about a plurality of positions including and between an open mode and a closed mode as a function of the at least one dynamic parameter of the motor vehicle when in the dynamic mode, the controller configured to permit the valve to be in a position that is at least partly open at certain times when in the dynamic mode; the bypass channel configured to increase loudness of sound from the tail pipe (22, 22A) as the valve allows exhaust flow to bypass the noise-reduction portion of the muffler through the bypass channel.
