1. The flange is the right
size and and shape. It actually fits correctly and requires
no bending or adjustment. Once clamped to the manifold, it
will not come loose. By using a small amount of muffler sealer,
you can achieve a permanent seal to the manifold.
2. The Original Design provides for very
low backpressure. Less than 25% of the backpressure of
the low cost alternative. It's quieter but still
has the same "putt, putt" sound!
3. This means more power and a slightly
lower operating temperature at full load or high speed. Dyno
Tests have shown an 8% increase over the low cost muffler.
4. All tubing is the same size throughout
the tube; Mandrill bending is
used as originally specified, maintaining the full cross-section
at all points along the pipes.
