Designed specifically for cars with an emphasis on low and medium speed range that is easy to handle on the street. The pipe is closer to the straight shape and gradually thicker towards the rear side to reduce power down in a lower speed range due to pressure loss and improve torque. ● Provides linear acceleration response and comfortable sound so you can feel the sheer breasts throughout the entire area. Uses beautiful all-stainless steel (SUS304) that has excellent corrosion and rust resistance, and the bullet-type tail end design makes the rear styling more sporty. D-SPORT does not have an inner silencer setting.
