A system for improving performance of an internal combustion engine is provided. The system may include an exhaust pipe and a leading edge member attached at one end of the exhaust pipe. In one aspect, the leading edge member may be attached to a windward side of the exhaust pipe to define a drawtube arranged to lower a pressure at the end of the exhaust pipe. A device for lowering a pressure at the end of a vehicular exhaust pipe to improve performance of an internal combustion engine may also be provided. The device may include a substantially planar leading edge member and a sleeve configured to be secured to a vehicular exhaust pipe. A bottom edge of the leading edge member may be attached to the sleeve.
