DIVERGENCE EXHAUST PIPE COMBINATION MEANS OF TWIN MUFFLER FOR MOTORCYCLE

摘要

The present invention relates to a branch pipe coupling structure of the twin muffler for motorcycles, and can improve the exhaust noise damping performance, ever reducing the back pressure decreases the output.; The present invention by forming the main exhaust pipe (1) at each end of the branch pipe (2), a semicircle section by forward a predetermined length of (3) (3 2 ') of a circular cross-section by mutually overlapping the flat parts of semicircular section ( 3 and 3 '), the will of hayeoseo parallel coupled to the main exhaust pipe (1), the aforementioned branch pipe (2) (2' semicircular section (3) (3 ') after a), by forming a section in a circular shape that to increase, and at the same time the branch pipe (2) is parallel to the main exhaust pipe (1) and branch pipe (2 ') is to be formed into arc-shaped form the end parallel to the branch pipe (2) amounts manifold cross-sectional area (2 ) (2 is the hayeoseo ') at the end of the muffler (22) (22' connect).; In addition, a slit 4 formed in the one positive branch pipe (2) (2 ') of semicircular section (3) (3') the front flat portion main exhaust pipe is inserted to the outside of the main exhaust pipe (1) (1) ( was inserted in 4 ') is a weld joint hayeoseo.
