Abstract
An exhaust system includes a muffler, an inlet pipe, and an exhaust pipe. The muffler includes an inlet hole adapted to receive the inlet pipe and an outlet hole to receive the exhaust pipe. The inlet pipe has a first and second linear portions extending from a radiused portion, the first and second linear portions being generally perpendicular to one another. The radiused portion and the first linear portion of the inlet pipe are positioned within the muffler. Portions of the inlet pipe and exhaust pipe located within the muffler may optionally include perforations and be closed off.
Claims17
A reduced noise muffler for use with an exhaust system comprising:
- a hollow shell member having a first end, a second end, a first inlet opening, a second inlet opening and an outlet opening, said first end opposing said second end along a longitudinal axis;
- a first inlet tube for receiving exhaust gases, said first inlet tube passing through said first inlet opening and having a first linear portion, a second linear portion and a radiused bend located between said first and second linear portions, wherein said first linear portion of said first inlet tube is positioned within said first inlet opening;
- a second inlet tube for receiving exhaust gases, said second inlet tube passing through said second inlet opening and having a first linear portion, a second linear portion and a radiused bend located between said first and second linear portions, wherein said first linear portion of said second inlet tube is positioned within said second inlet opening;
- and
- an exhaust pipe to permit the exhaust gases to exit said hollow shell member, said exhaust pipe extending through said outlet opening;
- wherein the second linear portion of said first inlet tube and the second linear portion of said second inlet tube are positioned within said muffler substantially coaxially and are generally in parallel alignment to each other and the longitudinal axis of said hollow shell member.
A reduced noise muffler for use with an exhaust system comprising:
- a hollow shell member having a first end, a second end, an inlet opening, and an outlet opening;
- an inlet tube for receiving exhaust gasses, said inlet tube passing through said inlet opening and having a first linear portion, a second linear portion and a radiused bend located between said first and second linear portions, wherein said first linear portion is positioned within said inlet opening and said a second linear portion and said radiused bend are positioned within said hollow shell member;
- and
- an exhaust pipe to permit the exhaust gasses to exit said hollow shell member;
- wherein said muffler is devoid of baffles, transfer tubes, and multiple expansion chambers to maximize the size of a single expansion chamber within said hollow shell member
