This Graves Motorsports Cat Eliminator exhaust is designed for the racer on a budget seeking the closest performance exhaust to a full race system. Graves Motorsports did not allow compromises in the development of this system. Material diameters, lengths, the silencer core size and length are optimized for maximum power output throughout the throttle and RPM range. This Graves Motorsports slip-on exhaust system is built using the same Championship design and craftsmanship found in every Graves Motorsports Exhaust and is hand-made in the USA! This high performance exhaust system features either stainless steel or titanium tubing (most models) that eliminates the restrictive catalytic system with your choice of carbon fiber or titanium silencers (most models). Graves silencers feature conical titanium - standard satin finished or the polished "Showstopper" version - or carbon fiber endcaps. Graves uses the same 1.00 mm thick wall high-heat grade titanium tubing used on their Superbikes. This material is designed special for maximum durability and oxidation resistance up to 800°Celsius / 1472°Fahrenheit. It is designed to live at almost twice the temperature of normal Grade 2 titanium. The tubes are precision bent and cut with the latest equipment available. The tubing is then welded in fixtures designed so that repeat-ability is second to none. Graves Motorsports' "Everlast" packing produces an exhaust note like no other, and holds up longer to the extreme conditions of a high revving motorcycle. This full exhaust system delivers exactly what your bike deserves: increased POWER, lasting durability, weight loss, IMPROVED style and sound.
