Two Brothers Racing has improved on the already amazing GSX-R1000 07-08 models with their M-2 single slip on system. By getting rid of the left side muffler and routing all the exhaust into the M-2 muffler, they saved a whopping 20lbs. Bringing the claimed dry weight of the Suzuki GSX-R1000 07-08 from 379 lbs. to a lean 359 lbs. You will definitely notice the 20lb. weight savings on the track or street, not to mention a significant HP and Torque increase all throughout the RPM range. The M-2 exhaust and the GSX-R1000 07-08 are sure to continue being a winning combination. For the traditionalist, there s a dual flange version of the M-2 exhaust system. The dual systems offer significant power gain and reduced weight while maintaining the dual exhaust look and sound. POLISHED ALUMINUM: Aluminum is a lightweight and strong material used extensively in the aerospace, automotive, and of course, motorcycle industry. Aluminum is a wise choice due to its excellent strength to weight ratio, corrosion resistance, and clean look. We use 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 mirror polished finish. Ounce for ounce, aluminum is the best value of all the M series mufflers. As a rule, the aluminum mufflers weigh about 8.3oz. more than Titanium or Carbon Fiber mufflers. CARBON FIBER: Two Brothers has been using Carbon Fiber in motorcycle mufflers since 1992. They are currently the only US 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. The 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. TITANIUM: By weight titanium is one of the world s strongest readily available metals, making it ideal for the M series 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 it is able to use a very thin (.024 ) material to construct the Titanium muffler. The result is a muffler that is about 8.3oz. lighter than the M series aluminum mufflers. Titanium has become an industry standard for motorcycle mufflers due to its durability, corrosion resistance, lightweight, and factory look.
