The table below highlights the mileage improvement when using the Vector exhaust technology, shown in both mpg gain and percent improvement.

Relative noise comparison demonstrates the competitive products range from 1.3 times louder to 11.1 times louder than the Vector Exhaust Technology.

At the 1200 rpm level the Vector exhaust technology demonstrated a 19.4% lower backpressure reading than the Competitive A muffler and a 22.9% lower backpressure reading, than the Competitive B muffler.

At the 600 rpm level the Vector exhaust technology demonstrated a 64.0% lower backpressure reading than the Competitive A muffler. The Competitor B muffler’s backpressure was so high that it could not be comparatively measured as it was outside of the test limit range.
