While Im on this thread about back pressure let me say this all 2 strokes need back pressure 4 strokes require very little if any at all. Motorcycle exhaust baffles serve two purposes.

A motorcycle backfire happens because of the presence of uncombusted fuel in the exhaust pipe.

Motorcycle exhaust back pressure. This issue is caused by. For instance I have a certain brand of motorcycle. Maintain exhaust velocity but as RPM climbs and exhaust volume increases the second path is opened to curb backpressure - since there is greater exhaust volume there is no loss in flow velocity.

Consider the ultimate low-restriction exhaust system. Hope this help everyone to understand when it is and is not needed. Check the exhaust pipe for leaks at the header gaskets and if you have a 2 part pipe muffler and headers are 2 separate parts check the band clamps and gaskets there.

My limited knowledge tells me that to keep backpressure the same and. Turbo or modified race engines drop the exhaust pressure as low as you can. The trick is to have a pipe that that is as narrow as possible while having as close to zero backpressure as possible at the RPM range you want your power band to be located at.

Back pressure is a term that misleads many into thinking it is a beneficial characteristic that somehow their engine needs back pressure to operate correctly. Too short of exhaust. Backpressure in its most extreme form can lead to reversion of the exhaust stream - that is to say the exhaust flows backwards which is not good.

In a four-stroke system as the exhaust valves begin to open a pulse of exhaust pressure enters that cylinders header pipe. I have worked on dozens of motorcycles over the years and backfire issues seem to come around every once in a while. If you want to maximize horsepower the thinking goes you have to minimize backpressure.

Back pressure may be a byproduct or symptom but is not the goal. Reduce the noise from wide-open exhaust pipes and create back-pressure in the exhaust system. BMW and Nissan use a simpler and less effective method - there is a single exhaust path to the muffler.

The low-speed routing shown here is. Back pressure at its most extreme form can lead to reversion of the exhaust stream - that is to say the exhaust will flow backwards which iser. Wasting fuel and increasing pollution and.

The misunderstanding comes into play as we seek to increase exhaust gas velocity by restricting tubing diameter restriction ie. This drag results in a pressure drop through the pipe. Its pretty obvious that the engine has to produce this pressure differential so the less power it has to spend making pressure to push the exhaust out the more power it can.

You can do this using smoke so get out the incense cigarettes cigars etc or just blow out a match and with the bike running pass this smoke around the exhaust ports andor the junction of the headers to the muffler. In order for the fluid to flow at all the pressure on one end of the pipe must be higher than at the other. 3rd Gen Z1000Z1000SXNinja 1000.

Kawasaki Z1000 Ninja 1000 Z800 Z750 Z-750S. Exhaust phase of the cycle back pressure is. The exhaust valve in the latest Yamaha YZF-R1 not only regulates back pressure but it actually reroutes exhaust flow based on engine speed and load.

Limiting noise emission is not only considerate but is required by law in many localities. In an exhaust system that pressure drop is what we refer to as back pressure. The trick is to have a pipe that that is as narrow as possible while having as close to zero back pressure as possible at the RPM range you want your power band to be located at.

Find great deals on eBay for back pressure exhaust. Conventional wisdom says exhaust backpressure is bad. When it reaches a point of.

FactoryOEM engines will require some retained back pressure to maintain the powertorque curve as nothing else in the engine has changed but still try to achieve as low as possible. Would removing the baffles on the stock exhaust system negatively affect the backpressure to the engine thus degrading performance.
