These equal length performance headers improve exhaust flow and sports car sound.
These headers will give your 458 a light increase in volume while the equal length design smooths out exhaust pulses for a smooth high pitched sound.
Often times headers are the best way to unlock power on a naturally aspirated engine. On our DynoJet we saw peak curve gains of 34 whp and 38 ft-lbs of torque at 4500 RPM. Theses gains are carried throughout the RPM band with peak horsepower increased by 13 whp.
NOTE: To ensure proper header seal, after initial heat cycle, tighten all exhaust bolts to the OEM torque specs
