B6A 4" Super Single Exhaust
The B6A 4" Super Single Exhaust is engineered for serious power and serious tone. Designed specifically for high output VR30 builds and daily driven cars. , this system maximizes flow while delivering a deep, refined sound that stands out without being obnoxious.
Starting with a high efficiency 3" Y pipe, exhaust gases from both banks merge smoothly before transitioning into a full 4" single exit. This configuration dramatically reduces back pressure compared to what's in the market, improving turbo response, midrange torque, and top end power.
The integrated resonator is carefully sized to control drone and eliminate harsh rasp, producing a deep, aggressive tone under throttle while remaining composed during cruising. It sounds like a performance car should, strong and clean.
