Overwhelming Low Exhaust Pressure - 50％ of Original Pressure
φ75 large diameter pipe and full straight structure reduce the exhaust pressure to 50% of the stock. This significant exhaust pressure reduction enables the turbine to run smoothly from low RPM range,which results in the engine output increase in an entire speed range. Also, this pressure reduction effect is enhanced as the tuning level becomes more advanced;the engine output can be increased to 540ps without engine power-loss.
