A portable, lightweight racer vehicle. The racer includes a body, a motor and a battery powering the motor, a motorized wheel, a first wheel, and a spring-loaded wheel to cause the motorized wheel to maintain contact with a surface upon which the motorized wheel rotates. The first wheel is larger than the motorized wheel and the spring-loaded wheel. A tube section includes a first half section having a pair of interlocking fingers and a pair of notches; and a second half section having a pair of interlocking fingers and a pair of notches. The two halves are removably snap-fit or press-fit together by joining the pair of interlocking fingers of the first half section with the pair of notches of the second half section while simultaneously joining the pair of interlocking fingers of the second half section with the pair of notches of the first half section. A splitter pipe includes a body having an input port and at least two output ports, and a remotely controlled valve between the input port and the at least two output ports. The splitter pipe is non-opaque, and an inner diameter of the input port does not exceed 2 inches.
