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 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 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 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 as the valve allows exhaust flow to bypass the noise-reduction portion of the muffler through the bypass channel . <EOS>
