Do 2 strokes need a silencer?

Well-Known Member What they need is the reversion pulse that the expansion chamber makes. The stinger (silencer or no silencer) length has very little effect on performance. Back pressure can really screw up a 2 stroke motors power band.

How does a 2 stroke silencer work?

A two-stroke pipe uses its reflective pressure wave to keep the fuel/air mixture inside the combustion chamber. Most of this tuning is done in the pipe itself, but muffler length and diameter play a part. There is no power difference between one brand’s high-end and low-end pipes.

Can you use a 2 stroke silencer on a 4-stroke?

The expansion chamber from a 2-stroke would not work well on a 4-stroke. If you go with two silencers, be sure the pipes are long enough between the exhaust and the silencer.

What does on the pipe mean 2 stroke?

The term refers to the range of RPM where the two stroke pipe is boosting power. On old two strokes before power valves came out, two stroke engines produced a four stroke like spread of power that built smoothly toward peak power and rolled over gradually thereafter.

Why are 2 stroke exhausts big?

That bulge is called an expansion chamber, and it is used to increase the horsepower of the engine (see this page for a photo). The basic idea behind an expansion chamber is to use the momentum and pressure of the exhaust gases to create a pump that squeezes more air and fuel into the cylinder during the intake stroke.

Why do two strokes have a big exhaust?

On a two-stroke engine, an expansion chamber or tuned pipe is a tuned exhaust system used to enhance its power output by improving its volumetric efficiency.
