Aluminum is a very lightweight and strong
material used extensively in the aerospace, automotive, and of course,
motorcycle industries. Aluminum is a wise choice due to its excellent
strength to weight ratio, corrosion resistance, and clean look. Two Brothers
Racing uses lightweight thin wall .060” extruded 6061 aluminum alloy that is
heat treated to a T-6 condition for increased strength, durability,
hardness, and finish hold. After the aluminum has been heat treated, it is
cut to length and given a brushed satin finish. Ounce for ounce, aluminum is
the best value muffler. As a rule, the Two Brothers Racing aluminum mufflers
weigh about 8.3 oz. more than carbon fiber or titanium mufflers.
Two Brothers Racing has been using carbon fiber
in motorcycle mufflers since 1992. They are currently the only U.S. Company
to exclusively use Filament Wound Carbon Fiber (FWCF) on every carbon fiber
muffler they sell. They draw on only the best high temperature resins and
control a proprietary lining system adopted from spacecraft, for additional
heat resistance. Two Brothers Racing FWCF is continuously wound over a
precision machined mandrel for a 100% seamless bond. The FWCF tube is then
cured in a high temperature autoclave oven for superior strength and heat
resistance. These crucial elements meld to form a precision lightweight
muffler that will perform as well as it looks.
By weight, titanium is one of the world’s
strongest readily available metals, making it ideal for mufflers. It is 45%
lighter than steel with comparable strength and twice as strong as aluminum
while being only 60% heavier. That’s right, titanium is HEAVIER than
aluminum, but since it is twice as strong Two Brothers Racing is able to use
very thin (.024”) material to construct their titanium mufflers. The result
is a muffler that is about 8.3 oz. lighter than the aluminum mufflers.
Titanium has become an industry standard for motorcycle mufflers due to its
durability, corrosion resistance, lightweight, and factory look. |
