Need to know where to find the best prices on motorcycle exhaust pipes?***bike bandit link.shtml***
Then start right here!
The right motorcycle exhaust pipes can completely change the look and performance of
your motorcycle. Exhausts can be elegant, sleek looking pipes or totally overwhelm the bottom
side of the bike with chrome, chrome and more chrome! Alternatively, they can increase the power output
from your engine by a considerable amount. And its certainly not beyond someone with a basic "hands on" aptitude to change the motorcycle exhaust pipes on their bike. But all this is jumping the gun a
little bit. Let me start from the beginning... The purpose of the motorcycle exhaust pipes (and the rest of the system) is
to direct the gases coming out of the combustion chamber away from the
machine (and more importantly the rider) to cool the exhaust gases down
and (sometimes, but not always) to make them quieter! If the hot exhaust gases were expelled straight from the exhaust port, the
front tyre would be in danger of melting and the noise would be unbearable. Even
worse (if it could get worse) any residual fuel in the exhaust would burn off on
contact with the air. The motorcycle exhaust pipes direct the gases
down and to the back of the machine. This allows them to cool , which minimises
any likelyhood of unwanted combustion. If you are in any doubt about how hot
exhaust gases can get, I suggest you get hold of a DVD of "The Great Biker Build Off" There is a classic episode in which Billy Lane is riding one of his
creations to a bike show when the ill directed exhaust pipes on his bike cause
his pants to catch fire! Priceless! Just as importantly, the arrangement of the motorcycle exhaust pipes uses the
pulses created during combustion to help the process of filling and emptying of
the combustion chamber with the combustion mixture. Silence is golden... Given that the good old internal combustion engine basically creates a series
of little explosions to give us that forward propulsion of our two wheeled
babies, its not surprising that exhaust gases are generally very noisy. So that
the motorcycle exhaust pipes can comply with noise regulation they need to pass
through a muffler, or silencer. the terms are at best a little optimistic (and
when you listen to some of the custom choppers, downright misleading!) but they
do a pretty good job for all that. The object is to allow the gases to pass down
the motorcycle exhaust pipes as freely as possible, while absorbing the surplus
energy which we recognise as noise, and occasionally music! Quite often this is achieved by absorption; the gases flowing at speed down
the motorcycle exhaust pipes are slowed down by allowing them to expand into the
body of the muffler. The noise energy is broken down further by obstructing them
with perforated baffles or through an expanded metal mesh and into a pad of
mineral wool. By the time the gases are coming out of the slash cuts on the end
of your motorcycle exhaust pipes, the noise has been subdued to a reasonable
level. The alternative approach is to break down the motorcycle exhaust pipes into
smaller compartments so that the exhaust gases are routed backwards and forwards
a bit like travelling through a maze. The sound waves are reflected against the
walls of the compartments, losing a little bit of their enegy each time, until
when they exit the tailpipe the noise is again at an acceptable level. More horsepower? Yes please..... It has been well known for years and years that a good exhaust set up can
increase the usable power generated by the engine. It is most obvious on two
stroke engines where the use of an expansion chamber can help to
"supercharge" the combustion chamber and give you a few free horsepower.
However, this effect can only be achieved over a narrow band of engine
speed . Better than nothing though... ...or the slip-on system... The full exhaust system is connected to the head of the engine and the
slip-on exhaust connects to the opening where your stock muffler is usually
found. Chreck out these online stores for all the accessories you need for a new motorcycle exhaust system! Bike Bandit
