Flowmaster - Tecnología de Silenciadores de Cámara
La tecnología básica del silenciador a cambiado muy poco a través de los
años. El cambió mayor en tecnología, ocurrió cuando fabricantes
empezaron a usar fibra de vidrio para mayor durabilidad.
Los silenciadores de cámara, como este Súper Serie 40, usan el gas de
escape y energía asociada para eliminar sonido no deseado, en ves de
simplemente absorber y perder la energía termo estática. Esto resulta en
la eliminación de sonido, y da por resultado lo que conocemos como el
Hay mucho mas en la tecnología de escape de gases que aparentemente. Aquí
en Flowmaster, continuaremos mostrando nuevos avances y desarrollando
nuevas técnicas para tubos de escape y así mejorar la "eficiencia y
rendimiento" de cualquier vehiculo que manejen.
Flowmasters Laminar Flow Technology
Flowmaster Laminar Flow Technology Explained:
Hot Exhaust gases entering the tapered
inlet section are actually accelerated as they pass through the perforated
cone into the outer core area. The perforation pattern and entry angle are
into each product to provide optimum airflow characteristics. The sound
energy is reflected and redirected
back into itself as well as into the outer thermal core by the carefully
selected taper angle of the entry cone.
2.Laminar Flow Area
The hot Exhaust gases are released and
allowed to expand into this section in multiple layers due to the tapered
angle of the entry cone. This produces a controlled laminar flow pattern
that reduces turbulence inside the muffler. Sound waves lose energy in this
section through the expansion of the Exhaust gases and reflective angles of the
cones, which direct the waves into the thermal barrier material.
The thermal barrier between the outer core section and the muffler case
provides a portion of the mufflers sound energy absorption characteristics.
This thermal barrier is engineered to deliver much lower exterior case
temperatures, allowing the muffler to be placed closer to heat sensitive
The increased surface area and angle of the tapered exit cone provide an
"easy exit" for the hot Exhaust gases
that encourages the flow out of the muffler. The carefully selected
taper angle of the exit cone directs and focuses the sound energy back into
itself. This convergence of sound waves reduces the sound level as it
passes out of the muffler.
How to Install Flame Throwers
Chaotic Customs, Mulvane KS
This video shows you step by step how to install flame throwers on your hot
rod. We used a kit from Speedway Motors to install them on a 1965
Thunderbird for the Chaotic Girls.
Flowmaster Super 40 vs Super 44?
This is my Silverado. I am debating installing the Super 40's or the Super
44's. What do you think?

How Flowmaster Mufflers Work
Flowmaster demonstrates how its straight-through and chambered mufflers
work. This video includes animated illustrations to show the
sound-deadening principles behind its chambered (baffled) mufflers with
delta design as well as its glasspack (straight-through) Exhaust mufflers.
Performance Muffler Upgrades [S2 Ep. 4-4]
In the world of hot rodding, when gear heads gather around and start
discussing their projects, invariably the conversation drifts into
speculation of what the smallest thing is that you can successfully put a
V8 engine in. Well today on GEARZ, Stacey pretty much puts an end to that
speculation by building a V8 powered BARSTOOL!! It's part go-cart... part
garden tractor... part insane... and ALL hot rod. Which of course is what
GEARZ is all about! If you like WILD.. then you don't want to miss this
show! Then Stacey dives into some Muffler Tech to show you what kind of
mufflers there are on the market, and give you some tips that might help
you make the right decision when the time comes to stick some cool mufflers
on your machine!
Sound Testing Hushpower Pro Series Mufflers
These Hushpower Pro Series mufflers can be used on a wide variety of
applications. During rigorous testing, they consistently delivered
performance equal to or better than open pipe systems, while dramatically
reducing sound levels across the rpm range. Hushpower Pro Series mufflers
feature T409 stainless steel internal construction covered by an outer case
manufactured from durable 18-gauge black aluminized steel.
