This system produced gains of up to +10 HP and +17 lbs. x Ft. TQ., as measured on our in-house dyno. This cat-back exhaust system is constructed of 2-1/2 IN - 3 IN mandrel-bent brushed finished 304 stainless steel tubing for maximum strength and durability. This system features a high-flow 304 stainless steel polished muffler, producing a deep sound. The muffler has a polished finish for ultimate corrosion resistance. 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. This system produces a deep sound unleashing all available horsepower and torque. Utilizing a factory style flange and hangers this system is a direct bolt-on system, which 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. 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.
