Abstract:
An exhaust system, comprising a LP-EGR system that couples an exhaust system to an intake system and an exhaust pipe within the exhaust system with a turn greater 90 degrees and less than 270 degrees between front and rear tires and upstream of a LP-EGR exhaust inlet; and a muffler positioned in the exhaust system downstream of the LP-EGR exhaust inlet and forward of the front tires. By shortening the LP-EGR path, back pressure to sustain EGR flow can be maintained without the use of a back pressure valve.
