Power, sound and good looks is what this Takeda cat-back exhaust delivers. Power gains of up to +11 horsepower and +15 lbs. x ft. torque as shown on our in-house dyno. 3"- 2-1/2" mandrel bent 304 stainless steel tubing and high flow transverse muffler offers maximum exhaust flow and incorporates a factory style exhaust valve to control the exhaust note. The valve utilizes the factory valve motor and factory performance modes. When closed, it directs the exhaust through the high flow muffler for a smooth, tuned exhaust note. When opened, the exhaust is allowed to bypass the muffler and unleash the sound and performance of your RS. The high flow, stainless steel muffler is finished in high temp, metallic black powder coating for long lasting good looks. Dual 4 1/2" stainless steel exhaust tips with laser etched Takeda brand logo for a custom finish.
