STI Exhaust Kit For WRX STI VA

An exhaust kit developed to provide performance-oriented WRX STI / S4 owners with a sense of unity with the vehicle. Based on the muffler that is standard equipment on the STI special specification car "S207", it is properly tuned for the standard car. The back pressure has been reduced by 40% or more to make the engine response to the accelerator operation more sensitive, and the acceleration performance has been improved so that the difference can be seen when starting or starting from a low-speed corner. In addition, the slash-cut tail pipe (101.6φ x 2 on one side) enhances the power of the rear view while producing high quality, and STI's original tuning adopts a safe and secure structure that does not affect the engine. We are particular about tuning the exhaust sound, and realized a high-quality and comfortable sound suitable for the character of WRX STI / S4.
