This cat-back exhaust system is constructed of 3″ to 2-1/2″ mandrel-bent brushed finish 304 stainless steel tubing for maximum strength and durability. This system features a high-flow stainless steel muffler, producing a powerful sound. Muffler finish may vary. Finishing off this exhaust system are dual 4-1/2″ diameter polished 304 stainless steel exhaust tips. The tips features a laser etched Takeda logo for a unique style. Utilizing factory style hangers, this is a direct bolt-on system that requires no cutting or modifications for a hassle-free installation. The factory-style exhaust valve provides a true bi-modal experience. In normal mode, all of the exhaust gases are directed through the muffler providing a deep, sporty tone. In Sport mode, the valve opens, allowing exhaust gases to bypass the muffler, providing an aggressive, crackling exhaust sound. The exhaust valve utilizes the factory valve motor (not included). A mitered merge collector is used to decrease turbulence and increase exhaust velocity, resulting in increased horsepower, torque, and improved throttle response. Stainless steel machined flanges and v-band clamps provide simple to install, leak-free joints. Utilizing state-of-the-art computer-aided design technology, this exhaust system is designed for custom, high tolerance factory fitment. 100% TIG welded for race-proven strength and durability. The Takeda cat-back exhaust shaves ten pounds of weight off your Supra.
