An exhaust pulse control unit and related method comprise an inlet tube communicating with incoming exhaust gas, an outlet tube communicating with exiting exhaust gas, and a housing extending between and connected with the inlet tube and outlet tube at opposite ends thereof. At least one pulse capture and expansion zone is disposed between the inlet tube and an intermediate zone portion of the housing, and is configured to increase exhaust manifold vacuum in an associated internal combustion engine. A first connector flange, having an attachment portion and central aperture, is connected with an inlet end of the housing. A second connector flange, having an attachment portion aligned with the attachment portion of the first flange and a central aperture, is connected with the inlet tube. The central aperture of the second flange has a beveled surface formed integrally therein to define a nozzle which forms the pulse capture and expansion zone. A fastener detachably, yet securely, connects the attachment portions of the first and second flanges to form an airtight seal between the inlet tube and the housing.
