A modular exhaust tube system for directing exhaust gases from an internal combustion engine. The exhaust tube system includes first and second elongate half-shells, with each half-shell comprising an elongate thin-wall body having a substantially U-shaped cross-sectional profile with a constant sideways opening along the length of the body. The exhaust tube system also includes a center brace having dimensions which span the length and height of the sideways openings. The sideways openings of the first and second half-shells are coupled together around the center brace to form a flattened elongate exhaust tube having an inlet end and an outlet end for directing exhaust gases from the internal combustion engine. In one aspect the first and second half-shells are selected from a group of interchangeable and modular half-shells having different substantially U-shaped cross-sectional profiles that are reversible top-to-bottom and end-to-end. |
