Harley Davidson Exhaust Back Pressure

Some owners believe that by removing the mufflers and installing straight pipes they are decreasing extra back pressure from stock muffler baffles and creating more horsepower.

Harley davidson exhaust back pressure. The most common part replaced on a new Harley-Davidson motorcycle is the exhaust system. The head pipes measure around 134 inches and 24 pounds in weight. Deeper sensor than those in most systems.

Home TAB Performance Resources Exhaust Back Pressure Back Pressure The most common part replaced on a new Harley-Davidson motorcycle is the exhaust system. When the two are equal the system is flowing almost perfectly but nothing is perfect in the real world except hummingbirds. With single pipes what is important is pressure wave tuning each exhaust pulse sets up a pressure wave that bounces back and forth between the port and pipe end.

The back pressure is the negative half of the sign wave the exhaust flow is the positive half of the sign wave. On the market today they range from about R6000 up to as much as R20 000. A common belief is that by reducing back pressure in the exhaust system you will automatically gain horsepower.

The rider often believes that by reducing back pressure in the exhaust system the engine will also increased. The worst you can do is free up some air movement - which is. I have used them on one of my TC builds with low back pressure set.

The system features minimal bending that gives the setup a clean appearance while decreasing any form of back pressure on your exhaust which increases overall performance and power. The holes are designed to help dampen and break the sound wave. The end of the hose is supposed to suck and the exhaust is supposed to blow.

VH designed this exhaust to be more than just a louder alternative and more of a proper performance upgrade. If while in operation you took an air hose and blew it up the exhaust that would create a back pressure in the exhaust effectively reducing the amount of suction at the hose end due to the air pressure up the exhaust. When installed inside the head pipes these cones act to repel the pulse waves as they return to the engine and alter velocity as the gas passes through the narrower passage.
