  • Extreme Low Exhaust Pressure Design for Supercharger/Turbo Tuning

    High exhaust efficiency is provided by the low exhaust pressure appropriate for supercharger and turbocharger tuning. The low-speed torque is improved, and high-speed torque can be improved with ECU ReFlash tool.
    Natural sound liaison while shifting from low to high speed range induces acceleration.
    Its comfortable & enjoyable exhaust sound may be loud, but it is appropriate level for street driving.

     

    more information

  • The standard sports muffler creates the exciting sound and provides comfortability of daily driving.

    The stock exhaust tips appear to be floating due to wide clearances between the tip and bumper and the size of the notch on the bumper. The 70mm dual exhaust tips on this product are well-balanced with the bumper notch, and the black chrome tips create a striking impression from the rear. Adding a little sound pressure to the original exhaust sound recreates the sporty sound quality making both daily driving and driving on winding roads enjoyable. Its moderate low-tone enhances the exhaust system's presence and the higher-tones imparting an elevated feeling to the driver.
